Please note that the creators of the Great Barrington Declaration say the following:

What is the role of vaccines in focused protection?

If wisely used, COVID-19 vaccines are an important additional tool for focused protection. The key is to vaccinate older high-risk people as well as their care givers, such as hospital and nursing home staff. Those who have already had COVID-19 do not need to be vaccinated.

Please go on our page Vaccines for more information on that subject.
