Are we close to a Covid-19 vaccine? | Vaccines and immunization

In March, Boris Johnson said we would change the situation in 12 weeks and “send the package for the coronavirus”, and by May ministers boasted that they would have the vaccine by September. Last week, the prime minister sounded far less confident, telling lawmakers that there was still no SARS vaccine, 18 years after it appeared. However, the vaccine may not be far off.


The World Health Organization is monitoring 1

96 vaccine studies. Of these, 42 have undergone human clinical trials and eight are in a third phase: large-scale trials to test their effectiveness. AstraZeneca and the University of Oxford have developed a vaccine based on a virus taken from chimpanzees, but the trial stopped a week after a volunteer fell ill – continuing in the UK but not the US. Another Novavax launched a larger phase III study after a study of 10,000 volunteers in the UK.

China and Russia have already approved some vaccines for limited use. The Wuhan Institute of Organic Products has a vaccine used for health workers in the United Arab Emirates and says the Chinese government has approved its use in more than 100,000 people. CanSino Biologics is testing its vaccine on Chinese soldiers. Vladimir Putin uses the pandemic for propaganda: he claims that the vaccine of the Russian research institute “Gamaleya” was approved in August (it is not), called it “Sputnik V” and is considered by the Ministry of Foreign Affairs to have authorized a campaign for misinformation aimed at AstraZeneca Trials.

Vaccine Working Group Chair Kate Bingham says there is a “small chance” the vaccine will arrive by Christmas. But she expects to be here until “early next year.” The vaccine regulatory authority must first approve each vaccine and then produce and distribute it. Pharmaceutical companies have already made millions of doses of some of the drugs under trial, but distribution may be more complicated. Many vaccines need to be kept refrigerated before use, so seven “Nightingale Vaccination Centers” have been opened, including Leeds City Hall and the Woking Entertainment Center, according to The Economist.

Will I be vaccinated?

Depends: Are you an adult, are you classified as clinically extremely vulnerable, or do you work for the NHS? If so, then you will most likely be at the head of the queue. But younger and healthier people who are not key workers are likely to have to wait much longer.

Lighting fixtures such as Sir Jeremy Farrar, director of the Trust Trust, said it would be immoral for richer countries like Britain and the United States to store vaccines while others fight for leftovers. Farrar believes that only 20% to 30% of the UK will initially need the vaccine.

A silver bullet?

We cannot be sure that vaccines will mean the end of locks. Scientists advise politicians to block to prevent the spread of the virus so quickly that hospitals are left without beds to treat patients – whether they have Covid-19 or another life-threatening disease. The first vaccines may be only partially effective and may not protect everyone. Influenza vaccines are only 50% effective, Bingham said last week. We may need masks and social distancing at least until July 2021.
