As Unlock 2.0 ends on July 31, it remains to be seen whether states resort to extension of lockdown in parts that are witnessing a surge in new cases of COVID-19. In the case of Mumbai, the city saw its lowest single-day spike in fresh cases on July 28.
This, even as states like West Bengal have announced the extension of complete lockdown in containment zones until August 31. Other states have also resorted to partial lockdowns in cities and districts with a relatively higher caseload.
Maharashtra Chief Minister Uddhav Thackeray recently expressed his reservations against a hurried lifting of the coronavirus lockdown in the state. He reportedly said he isn't US President Donald Trump and hence can't see his people suffer.
On the subject of the pandemic-led lockdown, CM Thackeray cautioned Mumbaikars. He said even as the city was making some progress in its fight against the virus, people should not let their guard down as yet. His views were also shared by his son Aaditya, who took to Twitter earlier today to highlight that Mumbai has reported 700 fresh cases today, a news he called "a major relief after 3 months".
Aaditya Thackeray did however reiterate the need to remain cautious as he said, "Caution: don’t let the guard down! Don’t let your mask down! Only get numbers down!"
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.
