Answers to your Covid vaccine questions – from how it works to when it is ready

Answers to your Covid vaccine questions - from how it works to when it is ready

A coronavirus vaccine prevents 90% of the disease, according to a large-scale clinical study.

Drug giant Pfizer and its partner BioNTech SE have not identified any serious safety concerns with the bump, from which the UK has already ordered 40 million doses.

This is a major breakthrough in the fight against the coronavirus and means the vaccine could be available in the UK by the end of the year – provided it is approved by regulators.

Pfizer and BioNTech SE are expected to seek approval for the US emergency later this month.

Here are the answers to your vaccine questions:

Is this big news?

Yes. These are interim results and the studies will continue. However, the analysis shows that the Pfizer vaccine can prevent more than 90% of people from getting Covid-19.

The vaccine has been tested on 43,500 people in six countries and no safety concerns were raised.
Pfizer plans to apply to the US Food and Drug Administration (FDA) for emergency approval to use the vaccine by the end of the month.

The analysis was conducted after 94 confirmed cases of Covid-19 were found among the study participants.

How does the vaccine work?

The sting is known as a messenger RNA (mRNA) vaccine.

Traditional vaccines are made using weakened forms of the virus, but mRNAs only use the virus’ genetic code.

An mRNA vaccine is injected into the body, where it enters the cells and prompts them to produce antigens.

These antigens are recognized by the immune system and prepare it to fight the coronavirus.

What are the benefits of this type of vaccine?

No actual virus is needed to make an mRNA vaccine. This means that the speed at which the vaccine can be made is accelerated dramatically.

As a result, mRNA vaccines have been labeled as a potentially quick fix to new infectious disease outbreaks.

They can also be modified relatively quickly if, for example, a virus develops mutations and begins to change.

mRNA vaccines are also cheaper to manufacture than traditional vaccines. However, both will play important roles in the fight against Covid-19.

Are you sure?

All vaccines are rigorously tested and monitored by experienced regulatory agencies.

Some believe that mRNA vaccines are safer for the patient because they do not rely on any element of the virus being injected into the body.
mRNA vaccines have been tested and tested in the laboratory and on animals, but the coronavirus vaccine will be the first to be approved for use in humans.

The human trials of mRNA vaccines, which have involved tens of thousands of people, have been going on since early 2020 to show if they are safe and effective.

Pfizer will continue to collect safety and long-term results from participants for two years.

Do we have enough doses to vaccinate the UK population?

The UK has received 40 million doses of the Pfizer / BioNTech vaccine – the first agreement the companies signed with a government.

It is believed that people need two doses, which means that not enough shots have been obtained for the entire UK population.

However, it is likely that other vaccines will soon release results from their clinical trials.

When will the Jab be available in the UK?

Downing Street said the UK will have 10 million cans to be dispensed if approved by the end of the year.

The Prime Minister’s official spokesman said: “The results are promising and while we are optimistic about a breakthrough we need to remember that there are no guarantees.

“We will know if the vaccine is both safe and effective once the safety data is released and only then can the regulatory authorities consider making it available to the public.

“In the meantime, the NHS stands ready to start a vaccination program for the most vulnerable people as soon as a Covid-19 vaccine is available before it continues to roll out.

“In total, we have sourced 40 million doses of the Pfizer vaccine candidate, 10 million of which will be manufactured by the end of the year and available to the UK if the vaccine is approved.”

Who will be vaccinated first?

The Joint Committee on Vaccination and Immunization (JCVI) has been looking into data on who has the worst results from the coronavirus and who is at the highest risk of death.

The preliminary guide states that the order of priorities should be as follows:

– Older adults in a nursing home and nursing home workers
– All people aged 80 and over, as well as health and social workers, even if they may be at the top of the list
– Everyone 75 and older
– People over 70 years of age
– Everyone aged 65 and over
– High risk adults under 65 years of age
– Medium risk adults under 65 years of age
– Everyone aged 60 and over
– All of those 55 and over
– Everyone aged 50 and over
– The rest of the population with priority yet to be determined
