Unequivocally …

Earlier this week I was asked by a friend about getting this year’s influenza vaccine, “Should I get a flu shot?” My answer was unequivocally … “Yes, especially if you have had flu shots in the past. In fact I got mine on the first day it was available.”

The conversation then switched to the Covid booster. “Should I get the next Covid booster?” Again my answer was unequivocally … “No, especially if you have already had Covid.” Keep in mind that my answer was not just because I got Covid fifteen days after I had my one and only booster, but my answer was based on the latest information on this issue out of Israel.

From Epoch Health:

“An Israeli study found that antibody levels after a fourth dose of the Pfizer BioNTech COVID-19vaccine returned to similar levels as after the 3rd dose after about four months.

The study, conducted among health care workers at the Sheba Medical Center, the largest hospital in Israel, found that the immunological protection of the 4th dose ‘was much smaller and had waned completely by 13 weeks after vaccination.’

It found ‘no substantial additional effectiveness over a third dose at 15 to 26 weeks after vaccination.’

The researchers tested the immune response of 6,113 employees and performed a monthly follow-up of the antibody levels in their blood. In addition, they performed a vaccine effectiveness analysis of 11,176 employees after the 2nd, 3rd, and 4th doses.

The weekly levels of antibodies throughout the period after the receipt of the 3rd and 4th doses were found to be similar and the study said were higher than after receiving the 2nd dose.

Effectiveness of the fourth dose against infection started at just 52 percent during the first five weeks after administration and dropped to negative 2 percent at 15 to 26 weeks. A growing number of studieshave detected negative effectiveness, which means the vaccinated are more likely to get infected.

The six-month follow-up study was published in The New England Journal of Medicine on Nov. 9.”

So there you have it unequivocally:

-flu shot … yes

-Covid booster … no
