Experts: Fully Vaccinated Don't Need Another COVID Shot

The video discusses the safety and effectiveness of mixing COVID-19 vaccines, particularly AstraZeneca and Pfizer. It highlights that AstraZeneca was not studied as a single dose and is not approved in the US. Johnson & Johnson's vaccine, using similar technology, is effective as a single dose. The National Institutes of Health is conducting trials on booster doses and vaccine mixing. The CDC currently does not recommend extra doses. Breakthrough infections are rare, with no evidence of higher rates in Johnson & Johnson recipients compared to mRNA vaccines. The video concludes that getting an extra dose is a personal choice, but the science is still uncertain.
