However, vaccine rollout in Europe has slowed down as Denmark, Iceland and Norway have suspended the use of the Oxford-AstraZeneca Covid-19 vaccine while the European Union's medicines regulator investigates whether the shot could be linked to a number of reports of blood clots, as reported by CNN.
Portugal has announced that it is suspending the inoculation of AstraZeneca's Covid-19 vaccine as a "precaution," joining other European countries - including France, Germany, Italy and Spain - in halting its use following reports of blood clots post-inoculation.
As of now, Denmark, Norway, Iceland, Bulgaria, Ireland, Netherlands, Germany, Italy, France, Spain, Portugal, Sweden and Luxembourg are the European countries that have suspended the AstraZeneca vaccine as a precautionary measure.
The European Medicines Agency (EMA) also said Monday that the benefits of the AstraZeneca vaccine outweigh the risks, adding that the number of people developing blood clots after vaccination does not seem to be higher than in the general population.
The agency said it would hold an emergency meeting on Thursday to advise on "any further actions that may need to be taken."
CNN further reported that the Australian government said it "remains confident" in the AstraZeneca Covid-19 vaccine after a growing list of countries paused the rollout of its use.
Chief Medical Officer, Professor Paul Kelly, said in a statement Tuesday, "there is currently no evidence that it causes blood clots."
Novavax on Thursday said final data from a trial in the United Kingdom shows its COVID-19 vaccine is almost 90 per cent effective, but the vaccine was far less effective in a separate trial in South Africa, given the virus variant there that has raised concerns about weakening vaccines.
According to The Hill, the data from the UK trial was very strong and similar to interim data released in January. The final data showed the vaccine is 96 per cent effective against the original virus strain, and 86 per cent effective against the variant identified in the UK, for the overall effectiveness of 89.7 per cent.
In South Africa, where a concerning variant is highly prevalent, the effectiveness was far lower, at 48.6 per cent, though it was a little higher, at 55 per cent, among people who did not have HIV.
The World Health Organization (WHO) on Friday issued emergency use authorization for Johnson & Johnson's coronavirus vaccine, paving the way for the one-shot dose to be used as part of the United Nation's international vaccine distribution effort.
According to The Hill, The go-ahead signal from WHO, which comes a day after the European Union approved the shot, means that countries that receive shots through the UN's COVAX effort, which promotes equitable distribution of vaccines, could cite the new endorsement in the distribution of the shot.
