Inactivated vaccines:When inactivated vaccines are made, the bacteria is completely killed using a chemical, usually formaldehyde. Dead pieces of disease-causing microorganisms (usually bacteria) are put into the vaccine. Because the antigens are dead, the strength of these vaccines tends to wear off...
they need to be aware of what parts of the immune system are online and what parts aren't fully active in people at each developmental stage. This is part of the reason some vaccines—such as for COVID-19—get tested and approved on different schedules for adults, teens, kids and babies...

The immediate goal is to create vaccines that destroy cancer cells—but some scientists are also testing vaccines that might prevent someone from developing cancer.
If you have COVID-19 you should restrict contact with your pet as much as possible to avoid passing it to them. To reduce the chance of your pet getting the virus from someone else, avoid letting your pet interact with people or animals that are not part of your household. ...
A bitter lesson of the past month is that viruses move fast. The good news of the deployment of the first COVID-19 vaccines was accompanied by the bad news that a new variant of the virus had emerged, quickening the disease's spread and pushing up the nu
Doctors will use a Pap smear, HPV test, or biopsy—along with their clinical judgment—to form a diagnosis and hopefully catch any high-risk cases before they become a problem. How someone is screened and tested varies based on their gender, age, and even sexual orientation. ...
Curran also has a larger, more existential concern when he considers the lessons of the AIDS and covid pandemics: “The problem is, if you bad-mouth Fauci and his successors so much, the next epidemic, people come around and they say, ‘Why should we trust these people?’ And the q...
necessary to develop a strong immune response against cancer – the first is the activation of killer T-cells (CD8+ cells) against a specific target on a cancer cell. This has been known for quite some time and many vaccines that were tested earlier were designed to work by activating ...
Not all vaccines in development require two shots. Johnson & Johnson is testing a single-dose vaccine. WHAT ABOUT SIDE EFFECTS? The experimental vaccines have been tested in tens of thousands of volunteers so far, and seriousside effectshave not been reported. Health officials will be monitoring...
