A number of social media users have shared a meme claiming that the Delta variant of Covid is a side effect of the vaccines. We fact-checked and found that the claim is false.
A screenshot is given below.
What is Delta variant of the Coronavirus?
Delta variant is a mutated (evolved) variant of the original Novel Coronavirus.
As World Health Organization (WHO) explains on its website, “All viruses – including SARS-CoV-2, the virus that causes COVID-19 – evolve over time. When a virus replicates or makes copies of itself, it sometimes changes a little bit, which is normal for a virus. These changes are called “mutations”. A virus with one or more new mutations is referred to as a “variant” of the original virus.”
WHO has termed the Delta variant as a “variant of concern” because of its increased transmissibility.
When was Delta variant of Coronavirus first identified?
As per the World Health Organization (WHO) the first documented evidence of Delta variant was in October 2020 in India. Below is a snapshot of the WHO website.
When were the Covid-19 vaccines invented?
In June 2020, China approved the CanSino vaccine for limited use in the military. In August 2020, Russia announced the approval of its Sputnik V vaccine for emergency use. But both these vaccines had limited availability.
The actual launch of the vaccine can be dated to December 2020 when the US FDA granted an emergency use authorization to Pfizer–BioNTech and the Moderna vaccine.
Hence the Delta variant of Covid-19 came up much before the vaccines were invented and administered.
