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. … [Read more...] about COVID-19 | Manhattan’s office buildings are empty.

After several more calls, he was offered the options of canceling his order or scheduling a new delivery date—September 9. But there was a big catch. It was possible the items might not be in stock, yet again, and by September 9 he would be in the exact same situation. He learned his local store would be restocked with the items August 1, but for whatever reason, that store couldn’t just ship them upon receipt.

(He also scored a $75 gift card for his troubles.) … [Read more...] about Ikea’s e-commerce was already pretty bad. During COVID-19, it absolutely fell apart
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. … [Read more...] about Coronavirus state-wise tally on September 5: Assam’s COVID-19 count rises to 1.2 lakh
All four virus strainsThe university research team led by Venkatramana identified all four strains of the virus causing dengue fever in Hyderabad for the first time. In 2019, Telangana saw a big spike with around 6000 dengue cases, with a peak between August-September.Dengue is caused by four types of viruses (DENV-1, DENV-2, DENV-3, DENV-4) belonging to the Flaviviridae family. They can cause mild to severe fever or potentially lethal complications such as haemorrhagic fever. … [Read more...] about New research improves understanding on dengue, but vaccine search continues
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. … [Read more...] about Coronavirus state-wise tally September 13: Total cases in Andhra Pradesh cross 5.5 lakh
