Alphabet Inc’s Google said it would require employees in the United States to be vaccinated for stepping into its campuses, in an effort to get its workers immunized against COVID-19.
The company said it would expand the vaccination drive to other regions in the coming months.
Many tech companies including Microsoft Corp and Uber have said they expect employees to return to office, months after pandemic-induced lockdowns forced them to shift to working remotely.
In April, Salesforce said it would allow vaccinated employees to return to some of its offices.
Google also said on Wednesday it would extend its work-from-home policy through Oct. 18 due to a recent spike in cases in different regions caused by the Delta variant.
Frequently Asked Questions
A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.
There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.
Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
