The folks who are fully vaccinated,may be excited about gathering with their family and friends again. They might even be planning a vacation. But there are still nagging questions about how long protection from the coronavirus vaccines will last. For instance, will your shot wear off gradually or suddenly? Will you need a booster?
Global health experts have criticized the USA decision as premature or even unethical, that eight months is too long and vulnerability can return as soon as five months after the second dose. The World Health Organization criticized the US for planning a third shot, while many nations around the world have not had their first yet.
Beginning September 20, Americans who received the Pfizer or Moderna vaccine should expect to receive a third dose. On the J&J vaccine, American health experts claim to be waiting for more data before recommending another booster shot. The wider angle of the bigger picture is that since there is a global vaccine shortage, and this announcement will only increase pressure on America to do more to vaccinate the rest of the world.
Physicians as well as medical ethicists are saying that it is difficult to justify a third dose for relatively healthy people given the current global need.
