COVID-19 Vaccines are effective, and a new study has forwarded their findings that show the immunization shot's effects on the human body and how it protects against the virus on the first dose. What the study said is that even at the vaccine's initial shot, it would be effective and would more likely protect against COVID-19, 21 days after the administration.

The risk of getting infected by COVID-19 is greatly reduced by the vaccine, and this is different from the initial studies and promises of the immunization dose that talks only about not getting its severe symptoms. 

Studies for the vaccine have been extensive and have provided a lot of information regarding the effects and benefits that it brings to humans, not to mention the harmful causes and side effects that are part of it. Pfizer and BioNTech have been one of the most regarded shots against COVID-19 with its mRNA-based shot like Moderna.

A recent study conducted by researchers from the Imperial College of London, entitled "REACT-1 round 12 report: resurgence of SARS-CoV-2 infections in England associated with increased frequency of the Delta variant" suggested COVID-19 would succumb against a vaccinated person after 21 days.

Vaccines take a long process of establishing themselves on one's body and letting every antibody it has, the knowledge to fight against the virus that has plagued the present days. The incubation period alone could take up to three to four days of projected fever, body pains, chills, and the like for it to settle in the body, but in 21 days, it would most likely be a full immunization. 

This is not to mention, the vaccine's first dose only, and it would be a massive change once getting the full dosage of the shot.

The swab tests that were carried out by the research show a lot of unvaccinated people that still make up the daily cases in the UK, but the good thing is that it has not affected much of the vaccinated population of the country.

Nonetheless, according to the report by New Scientist, 297,493 of vaccinated people against COVID-19 with the Pfizer and BioNTech's mRNA shot, only 0.8 percent have been infected with the virus. On the other hand, 0.3 percent were infected from those who have received Oxford's and AstraZeneca's.  

COVID-19 Vaccine: Is it Effective Against Strains? 

In the past weeks, the United States has been hit by a massive new strain called the "Delta variant," otherwise known as the "Alpha," which came from India. The country is aiming to double its efforts to achieve its goal of 70 percent of vaccinated adults by July, and it is still a long shot for the US and the Biden administration to reach this. 

The vaccine was said to also protect against strains, and it includes the most notorious ones from the UK and South Africa. Tests for the Delta are still under review.
