And countries such as the United Kingdom have wasted absolutely no time in administering the vaccine, with the first of 800,000 doses having been given at the start of this week.

However, despite this being an incredible milestone in the pandemic...

A warning has been issued after 2 patients have experienced side-effects from the vaccine.

U.K regulators issued the warning today.

It has been warned that people who have a history of "significant" allergic reactions should not currently receive the vaccine, according to local media.

The warning comes after 2 National Health Service (NHS) staff members who received the vaccine suffered an allergic reaction, the NHS in England has confirmed.

Although both staff members are recovering, the allergic reactions have been considered as major side effects to the vaccine and the risk factor is relatively high.

Professor Stephen Powis, the national medical director for the NHS in England, said:

"As is common with new vaccines, the MHRA has advised on a precautionary basis that people with a significant history of allergic reactions do not receive this vaccination after 2 people with a history of significant allergic reactions responded adversely yesterday. Both are recovering well."

This just goes to prove that people must remain vigilant for the time being.
