Vaccines have been under extreme scrutiny in the recent times. Many people have expressed their skepticism, wondering why such medication is necessary. This has been an increasing concern for the last few years. A 2018 study in the Human Vaccines and Immunotherapy journal also brought up the increasing barrier between vaccines and people who do not trust them. This divide was highlighted during the COVID pandemic; people led marches expressing the importance of self-autonomy, even though the contagious nature of the disease posed immense threat. People especially brought up how vaccines expose us to the same virus we are trying to be immune to, and how it could pose serious harm for people who are already immunocompromised. However, a new study shows that not only does it not pose a threat, but it also benefits people with cancer. Cancer patients are especially vulnerable to getting very sick from COVID-19. This is because their bodies might not be as strong at fighting off infections. But, a new study published in the JAMA Oncology, shows that COVID-19 vaccine boosters can be like a shield for them. These extra shots can really help prevent cancer patients from getting seriously ill, meaning they might avoid ending up in the hospital or worse. Boosters Significantly Reduce Hospitalizations Research has found that when cancer patients get COVID boosters, it lowers their chances of ending up in the hospital or in intensive care by nearly 30%. To put it simply, for every 150 to 166 cancer patients who got a booster shot, one person was kept out of the hospital or ICU. This is a big deal and shows just how helpful these extra vaccine shots are for people fighting cancer. Experts are saying that this benefit is very clear and encourages patients to talk to their doctors about getting vaccinated. Why Cancer Patients Need Boosters People with cancer often have weaker immune systems. This can be because of the cancer itself or because of the strong treatments they receive, like chemotherapy. A weaker immune system means their body isn't as good at fighting off germs and viruses. That's why health organizations strongly suggest that cancer patients get vaccinated against COVID-19, including the boosters. It gives their bodies a better chance to fight the virus if they come into contact with it. How The Study Was Conducted The study looked at information from a very large number of cancer patients – over 161,000 of them – treated at different hospitals and health centers. What they found was that not enough cancer patients were getting their COVID boosters. For example, at one point, only about two-thirds had received their first booster, and even fewer got later boosters designed for newer versions of the virus. It's not entirely clear why this number is low. It might be because patients are worried about the vaccine's safety, or maybe doctors aren't sure if it's okay to give the vaccine during cancer treatment. But what is clear, according to the researchers, is that we need to strongly encourage and help vulnerable people, like cancer patients, get these important vaccines. This large study really helps us understand how well COVID-19 vaccines work, and scientists will keep studying them as the virus changes to make sure patients get the best advice. Scientists aren't stopping here. They plan to look into how well these vaccines work for other groups of people whose immune systems are also not as strong. This includes people with diseases where their immune system attacks their own body, or those who have received organ transplants. By studying these different groups, we can learn even more about how vaccines protect people with various health challenges.
