Another vaccine is in the development stage, while trials of a third vaccine – from a Belgian company called Janssen – are underway in the UK.

Why do we need a vaccine?
If you want your life back to normal, then you need a vaccine. Especially now, when most people are still vulnerable to exposure to corona virus infection.
Only restrictive measures in our lives prevent more people from dying.
But a vaccine can teach our bodies to fight viral infections thereby preventing us from being exposed to viruses, or at least making them less lethal.
Getting a vaccine, along with better care, is the exit strategy for the pandemic.
Which vaccine is expected to work?
Pfizer and BioNtech are the first companies to announce the news about the final stages of their vaccine trials.
Company data shows the vaccine protects 90% of a person from Covid-19.
About 43,000 people have been vaccinated, and to date there have been no safety concerns.
Meanwhile, US company Moderna is running vaccine trials on 30,000 people in the US, half of whom are given a vacuum injection.
The company said the vaccine protected 94.5% of the people who were given the vaccine, after only five of the 95 trial participants who received the vaccine developed symptoms of Covid-19 later.
Trial results will also be released in the next few weeks on a vaccine being developed by British drugmaker AstraZeneca and scientists at the University of Oxford.
