In August, I previously expressed concern that this would be the case with the BA.5 bivalent booster erictopol.substack.com/p/the-imminent

A booster is your best shot now

Remember how vital the original boosters were to defend against Delta, Omicron, BA.2 and BA.5—reducing deaths and hospitalizations—as reviewed here. erictopol.substack.com/p/a-booster-is It all still applies. That's why they will help vs BQ.1.1 & the new variants with more immune evasion

Don't forget how well Singapore just withstood its XBB wave, a variant akin to BQ.1.1 with extreme immune evasion, with high levels of vaccines and original boosters (double the US %)

This is very good news. The XBB variant wave in Singapore is in descent moh.gov.sg XBB and BQ.1.1 are 2 of the most immune evasive variants and Singapore was the first country to experience a wave induced by one of them, now letting up

I wrote an addendum to contextualize the first human data for the BA.5 bivalent booster. The conclusion that a booster is your best shot to add protection vs new variants (BQ.1.1, in particular) stands

Time for nasal vaccine

Well, better than nothing

Is Novavax the answer to our problems ?

No. It’s India main and one of top UK vaccines. Look at how those countries have been decimated by wave after wave. We need a completely new typ of nasal vax and then n meantime:

and stay outdoors. It works with every variant and disease. 🤷🏻‍♂️

Wow... Something I did not expect. México didn't buy the new vaccines, I assume, that was not that bad after all.

We still have a lot of 1st gen vaccines. However, no 4 dose is still on the list

Please wear masks…

Wear high quality masks, improve ventilation and filtration.

Damn. Still, I gather that boosters are important.

Replying to

But it is an extra booster, so there's a small benefit from that. The nasal vaccine can't arrive soon enough, so we can at least see if that produces a bigger boost.

I was about to be mad but then I realized I would’ve needed a booster anyway because it’s been since last November that I could have one. I’m less mad now but pissed at gov for dropping once again, the ball on Covid response

Replying to

Discouraging.. Still good to get the new bivalent now though if you had your last original boost (I.e third shot), a year ago?

Replying to

and

It should be effective as a booster, even if it's not as helpful as was expected.

Replying to

so Eric, any chance you can inspire people to take precautions that do not wane, such as wearing low porosity masks like KN95s? Why no mention of masks, only mention of products that assume someone doesnt avoid infection. Please.

Have a hard time believing but even if produces a non-superior response it is still not inferior to the original AND immunity wanes after 6-12 months, so people need to be reboosted. But all studies like this will do is encourage blanket statements and avoidance

and

Immunity wanes much earlier than 6-12 months.
