WORLD Pfizer jab produces less antibodies against Delta variant of coronavirus: Lancet study

[womanofthehills]

LONDON: People fully vaccinated with the Pfizer-BioNTech vaccine are likely to have more than five times lower levels of neutralising antibodies against the Delta variant first identified in India compared to the original strain, according to research published in The Lancet journal.
The study also shows that levels of these antibodies that are able to recognise and fight the virus are lower with increasing age, and that levels decline over time, providing additional evidence in support of plans to deliver a booster dose to vulnerable people. It supports current plans in the UK to reduce the dose gap between vaccines since they found that after just one dose of the Pfizer-BioNTech vaccine, people are less likely to develop antibody levels against the B.1.617.2 variant as high as those seen against the previously dominant B.1.1.7 (Alpha) variant, first found in Kent. https://m.timesofindia.com/world/uk/pfizer-jab-produces-less-antibodies-against-delta-variant-of-coronavirus-lancet-study/amp_articleshow/83233320.cms?__twitter_impression=true

1. It's likely insignificant

There are still more than enough neutralizing antibodies to do their job. Other modalities also come into play.

2. Sounds like 40 yr old people will be fine

But a problem for older people who will be needing a booster.

4. Does anyone know when a booster might be available?

5. So, right now the data appears to suggest

Boosters probably won’t be needed - at least not soon. Looks like those injected or infected will likely produce antibodies for life
