Coronavirus vaccine:- UK signs deals for 90 million vaccine doses, The most awaited vaccine by now is now out 

The belgian pharmaceutical company Janssen and the US biotech company Novavax are developing the vaccine for coronavirus.

It means that the UK government has placed orders for six experimental vaccines, taking its potential stockpile to 340 million doses.

Most of the vaccines usually require only two doses. But in theory UK government took enough for everyone in UK to get atleast five doses.

With most of the vaccine trials ending in failure, the government is effectively hedging its bets, hoping that one of the vaccines it has purchased proves safe and effective.

The price at which these vaccines have been purchased has not been revealed.

The chairman of the UK government Vaccine Taskforce, Kate Bingham, told, “We don’t know if any of these vaccine formats that we’ve acquired will actually work. There are no licenced vaccines for any human coronavirus.”

She also added that it was a “priority” to ensure the UK has “sufficient vaccine" for groups “who are most at risk from coronavirus infection”.

Alok Sharma, the business secretary said, “The government strategy to build a portfolio of promising vaccine candidateswill  ensure we have the best chance possible of finding one that works.”

“Today’s agreement will not only benefit the people in UK but will also ensure fair and equitable access of a vaccine around the worldpotentially protecting hundreds of millions of lives."

The experimental coronavirus vaccines that the government has now purchased have been developed using four different scientific approaches:-

• Adenovirus vaccines: 100 million doses of oxford university/AstraZeneca; 30 million doses Janssen.
• mRNA vaccine: 30 million dosesBioNTech/Pfizer.
• Inactivated whole virus vaccine: 60 million doses of Valneva.
• Protein adjuvant vaccine: 60 million doses GSK/Sanofi; 60 million doses
