Thought I’d post a portion of a New York Times article examining the results of Israeli data on the 2nd booster. This may help in terms of timing one's booster for optimum protection. I'm not so concerned with getting seriously ill but do have some dread about the return to home Covid test. So if I could time the shot correctly it would provide me the best protection against infection. (See below)
*"The researchers compared the rate of confirmed virus infections and cases of severe Covid-19 among those who had received a fourth dose to those who had received just three doses. Protection against infection appeared to peak four weeks after the fourth shot: the rate of confirmed infections was twice as high in the three-dose group as in the four-dose group. By eight weeks after the fourth shot, however, the additional protection against infection had almost disappeared, the researchers found.
Rates of severe disease were 3.5 times higher in the three-dose group than the four-dose group four weeks after the booster shot, the researchers found. That protection did not appear to wane and actually ticked up slightly by the sixth week after the shot, when rates of severe disease were 4.3 times higher in the three-dose group."*
