Several lorries laden with vegetables and other essentials bound for Kerala are stranded at Makootam and other places on its borders with Karnataka as the neighbouring state has blocked roads, police said on March 28.
The Makootam road was blocked by Karnataka at around 4 pm on March 27 without any warning. Several lorries were waiting to cross the border, a police official here said.
At least 50 trucks, carrying vegetables and other cargo, had been held up at Makkotam since last night. Many stranded truckers alleged they were beaten up by police and asked to take the Wayanad route to enter Kerala.
Meanwhile, a pregnant woman from Kasaragod gave birth in an ambulance on March 27 after Karantaka police allegedly refused to allow the vehicle to take the woman to her doctor at Mangaluru.
Chief Minister Pinarayi Vijayan has already written to Prime Minsiter Narendra Modi on the blocking of roads and sought his intervention.
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.
