MRNA vaccines : Coronavirus vaccines being developed by Pfizer and Moderna could be the first mRNA vaccines to get approval.
Will vaccines stop the pandemic? : Headlines about safe and effective covid-19 vaccines seem simple, but the truth is that the trials tell us far less than we assume about who will benefit from a vaccine. The number of confirmed cases is more than 55.8 million, according to Johns Hopkins University, though the true number of cases will be much higher. The worldwide covid-19 death toll has passed 1.34 million. Switzerland recorded a daily average of 5262 coronavirus cases in the week leading up to 17 November. It also advised vulnerable people to write down in a will whether they would like to receive life support in the event that they become severely ill. All of the 876 certified intensive care unit beds in Switzerland are occupied, the Swiss Society for Intensive Medicine said in a statement yesterday.

It found that levels of coronavirus-specific T-cells had only decayed slightly at six months, while other antibody-producing immune cells called B-cells actually increased between one and six months after infection.ĭoctors in Switzerland said intensive care beds are at full capacity in the country. The study, which has not been published or peer-reviewed, included 41 people who had tested positive for the coronavirus at least six months prior.

The Pfizer-BioNTech trial will continue to collect data on the safety and effectiveness of the coronavirus vaccine for a further two years.Ī preliminary study suggests the majority of people who have recovered from covid-19 may still have coronavirus-specific immune cells in their bodies more than six months after infection. We still don’t know if either vaccine can stop infected people from passing on the virus or how long any immunity might last. The vaccine is based on similar mRNA technology to that used in the vaccine candidate being developed by US biotechnology company Moderna, which was found to be almost 95 per cent effective based on a preliminary analysis. The results are encouraging because older individuals are at an increased risk of becoming severely ill and dying from covid-19, in part because the immune system weakens with age. They said the vaccine worked similarly well “across age, gender, race and ethnicity demographics”. Out of 170 covid-19 cases among trial participants, only eight were in the vaccinated group, the companies said in a statement. About 40,000 people participated in the trial, with half receiving two doses of the vaccine and the other half a placebo.
Pfizer and BioNTech said they will submit a request for emergency use authorisation to the US Food and Drug Administration within days, which will allow the vaccine to be used with people outside the trial. The new data, from the first set of complete results from the phase III trial, also showed that the vaccine produced no serious side effects. Pfizer vaccine is 95 per cent effective overall and protects 94 per cent of people over 65įurther data about the coronavirus vaccine being developed by US pharmaceutical company Pfizer and German biotechnology company BioNTech shows that it is 95 per cent effective for all age groups, and protects 94 per cent of adults over 65.
