I think Biden shows why you should get your 2nd booster!

Otherwise you have no protection against getting the virus. I mean err...actually it doesn't matter? WTF...but Joe's symptoms are more minor than if he had one booster.


It is a vaccine right?


Biden had received a second booster. Here’s why it wasn’t enough to prevent infection.

President Biden received his second Covid-19 booster shot at the White House on March 30.

President Biden’s coronavirus infection is a stark illustration that the Covid vaccines, powerful as they are, are far from the bulletproof shields that scientists once hoped for.


Mr. Biden has received multiple doses of the Pfizer-BioNTech vaccine; his most recent shot, a second booster, was on March 30. Studies suggest that those doses will provide a powerful bulwark against severe illness — and indeed, the president has only mild symptoms so far after testing positive on Thursday, according to the White House.


But even booster doses offer little defense against infection, particularly with the most recent versions of the virus. What protection they do offer wanes sharply and quickly, several studies have shown. In the president’s case, the booster shot he received nearly four months ago is likely to have lost most of its potency at preventing infection.


Earlier in the pandemic, experts believed that the vaccines would be enough to forestall not just severe disease, but also the vast majority of infections. And that was true when earlier versions of the virus, including the Delta variant, swept the globe.


But the Omicron variant upended those hopes. As more of the population gained some immunity, whether from infection or vaccines, the virus evolved to dodge those defenses. BA.1, the subvariant of Omicron that circulated over the winter, was adept at causing infections even in those who had received a booster dose just weeks earlier.


Each subsequent avatar of the virus has become still better at sidestepping immunity. BA.5, which now accounts for nearly 80 percent of cases in the United States, is the most wily yet. Detailed data collected in Qatar suggests that immunity from previous infection and vaccines is weakest against BA.5 compared with its predecessors.


BA.5 is also highly contagious. The nation is recording roughly 130,000 cases per day on average; that number is likely to be a huge underestimate, because most people test at home or do not test at all.


The number of hospitalizations has also spiked over the past few weeks, although BA.5 does not appear to cause more severe disease than other forms of Omicron.


Given how much the virus has changed, the administration has been debating the value of authorizing additional shots of the original vaccine in the fall and offering second boosters to adults younger than age 50. An advisory panel of the Food and Drug Administration said last month that vaccine manufacturers should tailor shots to the newest variants.


But it’s unclear whether those shots will arrive in time to forestall a fall surge, and whether the virus will have once again evolved beyond their reach.
