The Centers for Disease Control and Prevention’s vaccine advisory committee will meet on Thursday and Friday to review the childhood vaccination schedule, look at adjuvants and possible contaminants, and revisit hepatitis B immunisation guidance.

This will be the third gathering this year of the Advisory Committee on Immunization Practices (ACIP) after Health and Human Services Secretary Robert F. Kennedy Jr. dismissed all 17 former members and brought in his own choices, many of whom have openly questioned long-standing vaccine policies.

It is also the first meeting since ACIP chair Martin Kulldorff, a former Harvard Medical School professor, accepted a permanent job at HHS. Pediatric cardiologist and former U.S. Air Force flight surgeon Dr. Kirk Milhoan will lead the committee during this session.

Hepatitis B: CDC Vaccine Advisory Committee Meeting

The latest battle in the US’ growing political, cultural, and scientific debate over vaccines will unfold inside a CDC meeting room in Atlanta later this week.

There, a key CDC advisory group — now entirely appointed by Kennedy who will vote on proposals that could significantly change long-accepted guidance meant to shield newborns from hepatitis B, a virus known to cause liver cancer.

The two-day ACIP meeting comes shortly after Kennedy instructed the CDC to alter language on its website, downplaying the agency’s long-standing statement that vaccines do not cause autism, even though extensive research has repeatedly found no connection.

Here is what public health experts say they will be watching during this week’s meeting, which will be livestreamed on Thursday and Friday.

Hepatitis B: Votes May Delay Or Limit Babies’ Protection Against Hepatitis B

According to the meeting agenda, Thursday’s discussions and votes will centre on major changes to hepatitis B guidance. Overnight, the committee released draft wording for two recommendations.

As per CNN, the first proposal would shift the current universal recommendation for newborn hepatitis B vaccination to an “individual-based decision” made by parents and a healthcare provider for babies born to mothers who test negative for the virus or whose status is unknown.

The language also gives parents and clinicians the freedom to “decide when or if their child will begin the HBV series.”

The second vote concerns draft wording that encourages parents to talk with clinicians about blood tests to check immunity levels before later hepatitis B doses. The draft states that insurance should cover these tests.

Currently, all newborns are advised to receive the vaccine shortly after birth to protect against infection from an undetected maternal case and from close contacts who may unknowingly carry the virus.

Committee members have previously urged better hepatitis B screening during pregnancy, while others have questioned whether only high-risk infants should get the vaccine.

Hepatitis B: How Contagious Is It?

Hepatitis B is highly contagious. It spreads through contact with infected blood and bodily fluids, often from people with no symptoms. While it can be passed during birth, through sex, or shared needles, it can also spread through shared items found in many homes: nail clippers, toothbrushes, and even certain pieces of jewellery.

Childhood And Adolescent Immunisation Schedule

It is not yet clear what parts of the schedule will be reviewed. The early agenda listed this topic for Friday without details. The final agenda shows that attorney Aaron Siri, a close adviser to Kennedy, will speak on this.

Critics, including Kennedy, have raised questions about the number of vaccines children receive and the timing between doses.

Discussion of “Adjuvants And Contaminants” In Vaccines

According to ABC News, the draft agenda included a Friday session on adjuvants and contaminants. The final programme describes the talk as examining aluminium exposure from vaccines before 24 months and rates of persistent asthma between ages 24 and 59 months.

Aluminum salts are used in several vaccines — including diphtheria, tetanus, acellular pertussis, hepatitis A, and hepatitis B—to strengthen the immune response, according to CNN.

The ACIP meeting also follows last week’s internal FDA memo claiming that Covid-19 vaccines may be connected to the deaths of ten children. Lakshmanan, O’Leary, and others say the committee could raise the issue during the discussions.

The US Centers for Disease Control and Prevention (CDC) has stated that an unvaccinated person who traveled to the US from Europe spread measles to 17 others in the country last year.

In a paper published in The Journal of Infectious Diseases, the CDC highlighted the case of an unvaccinated traveler who arrived at the Denver International Airport in Colorado in May 2025.

The person traveled with a fever, persistent cough, cold-like symptoms, and conjunctivitis (“pink eye”). He stayed overnight in a hotel and then boarded another flight to North Dakota. A day later, the person developed a rash.

“The index case was in an unvaccinated adult. Aircraft contact investigations identified 135 exposed domestic travelers. Fifteen secondary cases were identified among people exposed during the international (5) and domestic (3) flights, and at the airport (7),” the CDC said in the paper.

“Two tertiary case-patients were also identified. Five of the secondary case-patients had at least one documented prior measles vaccination,” it added.

The 2025 US Measles Outbreak

While measles was declared eliminated in the US in 2000, and sporadic outbreaks were controlled quickly, falling vaccination rates, especially during the COVID-19 pandemic, raise the risk of larger, harder-to-contain outbreaks.

This was further compounded by the anti-vaccine stance of President Donald Trump and his Health Secretary Robert F Kennedy Jr.

As per the CDC, a total of 2,281 confirmed measles cases were reported in the US in 2025. In 2026, the agency reported 10 new outbreaks, with more than 1,000 measles cases confirmed to date. More than 90 percent cases each year occurred in the unvaccinated.

Air Travel Increases Measles Spread

Recently, two passengers from India infected with measles landed in Auckland, New Zealand, via Singapore Airlines.

The Straits Times quoted Associate Professor Lim Poh Lian, group director of the Communicable Disease Agency’s (CDA) Communicable Disease Program, who noted that the individuals developed symptoms only while onboard the flight from Singapore to Auckland.

“Measles transmission may occur during travel. Travelers with fever and other overt signs of transmissible illness, such as coughing or malaise, should be strongly encouraged to delay travel while symptomatic,” the US CDC said.

Vaccination Key To Tackling Measles

Measles is a highly infectious disease characterized by the three Cs:

• Cough
• Coryza or runny nose
• Conjunctivitis or red and watery eyes

It easily spreads from one infected person to another through breaths, coughs, or sneezes and could cause severe disease, complications, and even death.

Even though a safe and cost-effective vaccine is available, in 2024, there were an estimated 95,000 measles deaths globally, mostly among unvaccinated or under-vaccinated children under the age of 5 years, according to the World Health Organization (WHO).

The CDC recommends that all travelers aged 6 months or older get vaccinated before international travel.

Sacred Games actress Rajshri Deshpande today informed of being diagnosed with grade 1 breast cancer and shared her journey of recovery.

In an Instagram post, the 43-year-old actress announced being diagnosed with the Infiltrating ductal carcinoma (NOS) -- the most common breast cancer type, accounting for roughly 80 percent of cases.

Importantly, the actress known for her work in Trial by Fire and Manto said that the deadly disease was detected during routine screening, initiating the road to early recovery.

“As you’re reading this, it means I’ve finally found the courage to tell my parents that I have been diagnosed with Infiltrating ductal carcinoma (NOS), a grade 1 Breast cancer. Now it’s time you all know,” the Instagram post read.

“We fortunately caught this early in a routine checkup, which gave us a fighting chance,” she added.

Rajshri called her treatment with ‘tons of tests and surgery” “a rollercoaster ride”.

“Trust me, it was everyone’s love and warmth that carried me through,” she said, while thanking her fans and her parents whose “faces after surgery melted my fears into unbreakable strength”.

“With everyone’s support, I feel am ready to take on the world,” Rajshri said, adding that she “is recovering beautifully and soon heading home from the hospital”.

What Is Infiltrating Ductal Carcinoma (IDC)

Also known as Invasive ductal carcinoma, the cancer occurs when abnormal cells growing in the lining of the milk ducts change and invade breast tissue beyond the walls of the duct.

Breast ducts are the passageways where milk from the milk glands (lobules) flows to the nipple.

Common symptoms of IDC include

• A lump or thickening in the breast or armpit area
• Changes in the size, shape, or appearance of the breast
• Nipple changes, such as inversion, discharge, or scaling
• Breast pain or discomfort
• Skin changes on the breast, like redness or dimpling

Key risk factors of IDC include

• Genetic mutations such as BRCA1 and BRCA2 gene mutations, and a family history of breast cancer
• Higher levels of estrogen
• Prolonged exposure to ionising radiation
• smoking
• excessive alcohol consumption
• obesity
• a sedentary lifestyle

Rising Early-Onset Cancers in women

The recent The Lancet Oncology study mentioned a rise in new cases in women aged 20-54 years (up 29 percent) since 1990.

Recently, American actress Christy Carlson Romano announced a positive cancer screening test.

Cancer is everywhere, said Romano, 41, in a tearful video on social media platform Instagram.

A 2025 study by Duke Cancer Institute in the US revealed that for women younger than 50, the risk of developing cancer is 82 percent higher than that of men, up from 51 percent in 2022.

The 2025 annual report from the American Cancer Society (ACS) also showed that cancer rates in young and middle-aged women are rising past those of men in the same age group, but especially among women under age 50.

Importance of Early Screening

As with Rajshri, catching cancer in its early stages can help individuals experience less severe symptoms, minimize discomfort, and improve overall quality of life.

Detection of cancer at an early stage can boost survival rates. It can increase the chances of successful treatment.

Common screening methods include

• Physical examination of your breasts by your doctor
• Mammography
• Breast ultrasound
• Breast magnetic resonance imaging (MRI)

Punjab is grappling with an outbreak of leptospirosis, a rare bacterial disease, with 36 confirmed cases, including 19 children who have been hospitalized.

The outbreak is part of a larger water‑borne infection that has affected 110 people so far in Hazara Singh Wala, a border village in Ferozepur district. The hospitalized children are receiving care at Ferozepur Civil Hospital and are reported to be stable, according to media reports.

Leptospirosis spreads to humans through contact with the urine of infected animals such as dogs and rats. The disease previously made headlines in 2024 when Punjab Chief Minister Bhagwant Mann was hospitalized after contracting it.

The state health department reports that the outbreak is affecting mainly children and young people aged 3-25, with nearly 90 of the 110 symptomatic patients being minors, most of whom are school-going children, the Indian Express reported. Commonly reported symptoms include fever, abdominal pain, and jaundice.

Alarm was heightened in the district following the death of 12-year-old Sehaj Kaur from suspected Hepatitis E on February 24.

Investigations revealed that contaminated water, including rodent droppings and dead pigeons, contributed to the outbreak, causing widespread concern among villagers.

Media reports stated that health officials in the states are taking steps to prevent further spread of the outbreak. They are conducting house-to-house screenings, distributing chlorine tablets and oral rehydration solutions, as well as repairing water supply lines to contain the outbreak.

What Is Leptospirosis

Leptospirosis is usually a disease of animals like dogs, mostly rats, and some farm animals. It has also been reported in pigs, zebras, and horses.

It mainly spreads via contamination or through direct contact with loosely available food items or water infected with rat urine.

Common symptoms include:

• very high temperature
• headache
• muscular pains
• vomiting
• diarrhea
• yellow or brown patches in the eye,
• abdomen pain

While the disease is usually self-limiting and treatable with antibiotics, in severe cases it can spread to the kidney, brain, spinal cord, and liver and lead to death. It can also cause pulmonary haemorrhage, leading to respiratory failure and death.

Leptospirosis In India:

The neglected zoonotic disease is endemic to India due to a tropical climate that complements the transmission of infection.

The first disease outbreak was reported in the 1920s in the Andaman Islands.

As per the National Centre for Disease Control (NCDC), India is expected to report 0.1-1.0 million cases per year, but less than 10,000 cases are reported.

Only four states, i.e., Kerala, Gujarat, Tamil Nadu, and Maharashtra, report more than 500 cases per year as per IDSP Disease Alert.

Andaman, Andhra Pradesh, Assam, Goa, Delhi, Karnataka, Odisha, Puducherry, and Uttar Pradesh also report cases.

Due to a lack of awareness of the disease and a lack of suitable laboratory diagnostic capabilities in most regions of the country, leptospirosis has been under-reported and under-diagnosed in India.
