Coronavirus vaccine: How long does COVID-19 vaccine immunity last?

Millions have already got themselves vaccinated and others are queuing up for the same.

However, questions about the vaccine's efficacy and the duration of immunity it provides still remains to be answered.

People are curious to know as to how long the immunity from the COVID-19 vaccination lasts?

How important is it to get the COVID-19 vaccine?

Considering the young and the elderly are both equally susceptible to the deadly coronavirus, it is important that each and every person, falling under the eligibility criteria, get themselves vaccinated.

Does COVID-19 vaccine provide immunity against the virus?

COVID-19 vaccines help our bodies develop immunity against SARs-COV-2 infection. It revs up the body's immune response against deadly pathogens and develops antibodies that provide lasting immunity for the future.

However, since the novel coronavirus is a new type of virus and COVID vaccines have just been developed, there's no solid evidence that could determine how well a person is protected after the vaccination or the duration of immunity it provides.

The study

A new report by the Centers for Disease Control and Prevention (CDC) looked into the data of 4,000 vaccinated healthcare professionals and frontline workers.

The study found that the messenger RNA (mRNA) vaccines developed by Pfizer-BioNTech and Moderna were effective in 80 percent of cases after the first dose and 90 percent after the second dose.

Additionally, they discovered that the vaccines reduce the risk of COVID-19 transmission by vaccinated individuals to others.

“Reducing the risk for transmissible infection, which can occur among persons with asymptomatic infection or among persons several days before symptoms onset, is especially important among healthcare personnel, first responders, and other essential and frontline workers given their potential to transmit the virus through frequent close contact with patients and the public,” the report stated.

How long does the protection last?

Researchers involved in the phase 3 trial of the Pfizer-BioNTech vaccines said that the immunization is prevalent for at least 6 months in vaccinated people. It found that the vaccine is 100% effective against the ailments listed down by the CDC and 95.3% effective against severe COVID-19 infections as referred to by the Food and Drug Administration (FDA).

In addition to that, the Pfizer-BioNTech vaccine is said to be effective against the South African variant known as B.1.351.

Should you continue wearing masks?

At the current stage, we cannot wholly depend on the COVID vaccines for immunity. It is important that we continue wearing well-fitted masks and practice social distancing.

Following all public health measures is crucial to contain the virus and protect ourselves and loved ones from the same.
