The Health and Human Services department has made a surprising announcement.  They want new vaccines to go through a specific type of testing before they are approved.  This testing involves giving half of the participants a placebo, which is usually just a saltwater shot.  This is to compare results with the actual vaccine.  This method is already used for new drugs and vaccines to check if they are safe and work well.

Some experts think this is a good idea.  They believe it is important to make sure vaccines do not cause more harm than good.  Others disagree.  They argue that it is unethical to give people a placebo if there is already a safe and effective vaccine available.  For example, giving half of the kids in a trial a placebo for the measles vaccine would put them at risk for the virus unnecessarily.  This is because there is already a proven vaccine for measles.

The department has not clearly defined what they mean by "new" vaccine.  It is unclear if this policy will affect the annual flu vaccine, which has been around for over 80 years.  The flu vaccine is updated every year to protect against the current strains of the virus.  It is also unclear if this policy will affect the annual COVID vaccines, which are also updated every year.

The department has said that they will follow the "Gold Standard of Science" when deciding what is a "new" vaccine.  This means that they will use the best scientific methods available to make their decisions.  The secretary of the department has long been skeptical of vaccine safety.  He believes that placebo-based trials are necessary to ensure that vaccines are safe and effective.

During the COVID-19 pandemic, COVID vaccines underwent placebo-controlled studies with over 100, 000 volunteers from diverse populations.  This was done to determine if the vaccines were not only effective but also safe.  Many childhood vaccines were originally tested with placebo trials.  Others have been available for decades, providing data from millions of people showing those vaccines are overwhelmingly safe and effective.

Once a vaccine for a disease is approved safe and effective, future versions of the shot are tested in clinical trials against the already approved shot.  Clinical trials test whether the updated vaccines generate an immune response that's comparable to or better than previous versions of the vaccine.  Even after vaccines are made available to the public, scientists continue to monitor them for safety.  They also review any reports of side effects or reactions and share these facts with the public.

The idea of using placebos in vaccine trials is controversial.  Some people believe it is necessary to ensure safety, while others think it is unethical.  It is important to consider both sides of the argument and make an informed decision.
