A British public health study has found that protection from either of the two most commonly used COVID-19 vaccines against the now prevalent Delta variant of the coronavirus weakens within three months.
It also found that those who get infected after receiving two shots of either the Pfizer-BioNTech or the AstraZeneca vaccine may be of greater risk to others than under previous variants of the coronavirus.
Based on more than three million nose and throat swabs taken across Britain, the Oxford University study found that 90 days after a second shot of the Pfizer or Astrazeneca vaccine, their efficacy in preventing infections had slipped to 75% and 61% respectively.

They should have went with MODERNA!
Congrats! #2 this time on the Shill-o-meter!
How do they know that the “Delta” variant is just that and not another Chinese bioweapon release?

Three months in a quarter. Drug companies report financials quarterly. Convenient.
Methods: We studied breakthrough infections among healthcare workers of a major infectious diseases hospital in Vietnam. We collected demographics, vaccination history and results of PCR diagnosis alongside clinical data. We measured SARS-CoV-2 (neutralizing) antibodies at diagnosis, and at week 1, 2 and 3 after diagnosis. We sequenced the viruses using ARTIC protocol.
Findings: Between 11th–25th June 2021 (week 7–8 after dose 2), 69 healthcare workers were tested positive for SARS-CoV-2. 62 participated in the clinical study. 49 were (pre)symptomatic with one requiring oxygen supplementation. All recovered uneventfully. 23 complete-genome sequences were obtained. They all belonged to the Delta variant, and were phylogenetically distinct from the contemporary Delta variant sequences obtained from community transmission cases, suggestive of ongoing transmission between the workers. Viral loads of breakthrough Delta variant infection cases were 251 times higher than those of cases infected with old strains detected between March-April 2020. Time from diagnosis to PCR negative was 8–33 days (median: 21). Neutralizing antibody levels after vaccination and at diagnosis of the cases were lower than those in the matched uninfected controls. There was no correlation between vaccine-induced neutralizing antibody levels and viral loads or the development of symptoms.

Minimal changes.
Delta variant has no changes in antigenic determinants.
This is junk science - or probably more junk reporting.
Sure wish you unvaccinated folks would go ahead and get a dose of that natural immunity so we can finally get to that elusive herd immunity. Since it works so good and has little risk of side effects /S

Our God-given, natural immunities are just fine, thanks.
We (USA) likely had, or were about to reach, herd immunity when these shots rolled out.
The shots are causing the variants/infections. But, we’ve known that would happen, per the early warnings given.
If you “VAX”d folks are ‘protected’....why worry one whit about the rest of us?
And, by all means....PLEASE DO keep YOUR masks on.
They don’t work, but...it will let us know who the highly virulent are. TIA.
And how long is the booster effective? Are we talking about booster shots every few months?
Ha! What do you mean by ‘effective’?
Ask FRAUDci....oh, wait....he is suppressing the CDC sponsored/ran reporting site, VAERS.
The first news stories said the vaccine lost some effect at 8 months.
Then it was 6 months.
Then 5 months, counting both shots.
Now 3 months.
In 2022 we’re going to need bigger vaccination cards with more lines.

Congratulations. You figured it out. No Sarc intended.
The main reason is there are animal reservoirs. Welcome to the “Dark Side” aka the unvaccinated.
FAUCI, ARE YOU LISTENING?….
