5 studies on quickly waning mRNA vaccines that make countries cut mRNA boosters time to 3 months/introduce 4th mRNA booster

Boosting by other jabs will prolong mRNA immune response

@JAMA_current: mRNA efficacy vs #Delta among elderly 20% after 4 months👇jamanetwork.com/journals/jaman…
2/5 According to Swedish data Pfizer vaccine’s efficacy against #Delta COVID strain is falling to below 30% after 6 months.

3/5 The UK Health Security Agency said those who had received three doses of Pfizer’s vaccine saw their protection against symptomatic illness caused by #Omicron variant drop to 45 percent within 10 weeks.

4/5 A live #Omicron virus study shows #Pfizer neutralization is 33x less than for “wild type” immediately after 2 doses and wanes completely in 6 months. Even after #Pfizer booster shot’s #Omicron neutralization drops 14x.
5/5 German study showed that 2 shots of Pfizer provide NO #Omicron neutralization at all after 6 months and only 25% neutralization 3 months after a booster.

1/4 Sputnik team has been the 1st to raise issue with quickly dropping efficacy of mRNA vaccines and relentlessly offered cooperation through mix&match/combo vaccine approach that works better against emerging mutations such as #Omicron and #Delta.

2/4 On September 17, 2021 we suggested that Sputnik Light booster will help Pfizer vaccine last longer.
3/4 We even offered to help “dress the Emperor up”

1/5 BREAKING: #SputnikV induces robust neutralizing antibody response to #Omicron, further strengthened by Sputnik Light booster, performing 3-7x better than other (including mRNA) vaccines. Light’s efficacy vs Omicron expected ~80% after 2-3 months.

2/5 Vaccines virus neutralization decrease against #Omicron:

Pfizer: 41x
Moderna: 49-84x
Sputnik V: 11.8x

Sputnik’s showed 3-7x less of a reduction than mRNA vaccines.
3/5 Virus neutralizing activity against #Omicron 2-3 months after Sputnik Light booster is higher than VNA vs “wild-type” virus 6 months after Sputnik V vaccination. Based on these data expected efficacy of Sputnik Light as a booster against Omicron could be more than 80%.

New study by Honduras' @UNAHoficial showed #SputnikV & Moderna or Pfizer combo is effective & safe.
It proves the success of mix&match approach, pioneered by #SputnikV. 1-shot Sputnik Light is ideal booster for mRNA, whose efficacy falls to below 50% 5 months after vaccination.
UNAH study found that combinations’ immune response exceeded that achieved with conventional homologous schemes.
Sputnik was world’s 1st vaccine cocktail, pioneered mix&match with other vaccines & offered 1-shot Sputnik Light as booster.
Sputnik V made an offer to Pfizer to start trial with Sputnik Light as booster on August 11, 2021.

BREAKING: #SputnikV will soon offer a booster shot, adjusted to work against the Delta variant of coronavirus, first detected in India, to other vaccine manufacturers. Below are the highlights of Sputnik V’s pioneering role in developing vaccine cocktails.
Sputnik V was the 1st #COVID vaccine cocktail in the world when created by the Gamaleya Center in April 2020. It uses heterogeneous boosting with 2 shots by 2 different adenoviral vectors Ad5 & Ad26 as we explained in this op-ed published nearly a year ago

Moreover, the vaccine developed by the Gamaleya Center against the Middle East respiratory syndrome coronavirus (MERS-CoV) in 2019, even before the novel coronavirus outbreak, was also a vaccine cocktail.

Os atrasos da Anvisa na aprovação do Sputnik V são, infelizmente, de natureza política e não têm nada a ver com acesso à informação ou ciência.
O Departamento de Saúde dos Estados Unidos, em seu relatório anual de 2020 há vários meses declarou publicamente que o adido de saúde dos Estados Unidos “persuadiu o Brasil a rejeitar a vacina russa COVID-19”.
O povo brasileiro aguarda a decisão do Supremo Tribunal Federal.

BREAKING: #SputnikV study shows that there are significantly more deaths following vaccination with Pfizer than with AstraZeneca vaccine per 1mn administered doses, based on official publicly available data by 13 international health regulators. Image
The causes of such major discrepancies in the number of death cases among different vaccines should be the focus of honest scientific and public discussion.
Death rates are below average in population due to selection criteria for vaccinations. Regulators didn't find connection between vaccinations & deaths. Instead of being silent on death number discrepancies among vaccines, the media should be covering facts and avoiding biases. Image
