8 weeks between shots is the’sweet spot’ for giving Pfizer’s two-dose COVID-19 vaccine, UK researchers say

Giving two doses of Pfizer's shot eight weeks apart could best protect against the Delta variant. A study found that the eight-week delay boosted immune responses higher than waiting 21 days. It's a trade-off between needing two doses and optimizing the immune response, the researchers said. See more stories on Insider's business page. LoadingSomething is loading. ...

You will know, or possibly be, someone who gets COVID-19 after a vaccine. Here’s what to expect, according to 2 people with breakthrough cases.

Breakthrough cases will become more common as the more transmissible Delta variant keeps spreading. But most disease experts still expect COVID-19 to be milder in vaccinated people. Two young people who got sick after they were vaccinated described how their symptoms progressed. LoadingSomething is loading. Breakthrough infections, or COVID-19 ...

BioNTech offers 10 times more antibodies than Sinovac | Digital Trends Spanish

A study carried out by the University of Hong Kong reveals that those who received the Pfizer-BioNTech coronavirus vaccine have ten times more antibodies than those who were inoculated with Sinovac. The work also shows that the latter group generates levels of proteins to attack the virus that would be similar or lower than those produced naturally in patients who have recovered from COVID-19. According to the researchers, the study results, which were published in Lancet Microbe, suggest the need for "alternative strategies", such as booster vaccines, for those who have been immunized with Sinovac, as a way to increase antibody levels in these patients. "The difference in neutralizing antibody concentrations identified in our study could translate into substantial differences in the ef...

Can vaccines increase breast size? | Digital Trends Spanish

The world had to accelerate research and the manufacture of vaccines to try to stop the coronavirus pandemic, therefore, it is possible that we still do not have knowledge of all the effects associated with drugs. Some of them may seem more unique than others, at least with respect to the comments of those affected themselves. Emma, ​​a young TikTok user, has pointed out on the platform that she thinks that the Pfizer vaccine may have increased the size of her breasts. The young woman assures that this would have started 15 days after having achieved the immunization of the vaccine. “It was kind of a crisis for me. I had to buy a bra one size larger, "he acknowledged. Although at some point it seemed almost anecdotal, the problem gained visibility when more women responded to the affec...

Pfizer will update its vaccine to defeat Delta variant | Digital Trends Spanish

Concerns about Delta variant have made many laboratories that already have their vaccines approved against COVID-19, have decided to start studies to tailor efficacy against this contagious strain. One such company is Pfizer, which this July 8 announced that it is already in the process of updating. "Pfizer and BioNTech are conducting tests to confirm this expectation," according to a press release issued late Thursday. Both labs, which have worked together on the vaccine called BNT162b2, will make this update to directly address the Delta variant. For now they are producing material for a clinical trial, which they expect to begin in August, pending regulatory approvals from the FDA. Third dose of Pfizer But that is not all, since Pfizer and BioNTech are looking closely at the situat...

Pfizer’s COVID-19 vaccine is less effective at preventing Delta infections than other variants, but still protects against severe illness, preliminary Israeli study says

Early data suggests the Pfizer vaccine is less protective against infection from the Delta variant. But it remains highly protective against hospitalization after infection. However, one expert said it was too early to precisely estimate the vaccine's effectiveness. See more stories on Insider's business page. LoadingSomething is loading. ...

Early findings indicate that mixing and matching coronavirus vaccines might improve your protection

The evidence in favor of a mix-and-match approach to coronavirus shots is growing.Early data from a UK study, though not yet been peer reviewed, indicates that mixing the Pfizer and AstraZeneca vaccines yields a greater immune response than two doses of AstraZeneca's shot. The researchers measured antibody levels among 830 volunteers who received either two doses of the same vaccine or a combination of Pfizer and AstraZeneca, four weeks apart.Volunteers who got AstraZeneca's shot followed by Pfizer's showed nearly the same antibody levels — and an even higher number of T-cells — as those who'd received two doses of Pfizer. By contrast, volunteers who got Pfizer's shot first and AstraZeneca's second had slightly lower antibody...

Mixing vaccines increases protection against COVID-19 | Digital Trends Spanish

The scientific community received preliminary good news this Monday, June 28, since A study of the University of Oxford indicated that the combination of vaccines is more effective in protecting against COVID-19. The expert and project leader, Matthew Snape, specifically addressed the AstraZeneca and Pfizer mix and in any order of administration. In the first run of the study, 830 volunteers were given one of four vaccine combinations. Some received two doses of Pfizer or AstraZeneca, which have been shown to be effective against Covid-19. Others received a dose of AstraZeneca, followed by a dose of Pfizer, or vice versa. One of the downsides was adverse effects, as the researchers found that volunteers reported more chills, headaches and muscle pain than people receiving two doses of...

Some experts who had Johnson & Johnson’s single-dose vaccine are now getting extra shots of Pfizer or Moderna to try to protect against the Delta variant

Some experts who got Johnson & Johnson's one-dose vaccine are topping it up with a dose of Pfizer or Moderna. They did it for extra protection against the fast-spreading Delta coronavirus variant, they said. The FDA and CDC don't recommend getting an extra shot, after a J&J vaccine or otherwise.

Measure the effectiveness of Pfizer and Astrazeneca against Delta | Digital Trends Spanish

An important study from the University of Oxford revealed the level of effectiveness of the Pfizer and AstraZeneca vaccines against the contagious Delta variant of COVID-19. The study, published in the journal Cell, looked at the ability of antibodies in the blood of people, who were vaccinated with the two-injection regimens, to neutralize the highly contagious Delta and Kappa variants, according to a statement. In fact, a few days ago he had settled in Britain for the Public Health England, that the two doses of either of the two vaccines, would help 90% in avoiding hospitalization for Delta.
