Spain is dealing with the highest ever number of coronavirus infections, with some regions considering further curbs on social life ahead of the end of the year.
Updating pandemic figures for the first time in four days, health authorities reported 214,619 new cases late on Monday, bringing the 14-day national caseload to a pandemic record level of 1,206 new infections per 100,000 residents.
At the height of the January surge, which until now was the one that infected most people in Spain, the rate had surged to 900.
The explosive spike is largely blamed on the omicron variant, which scientists say spreads faster than previous strains although the number of infected patients who need hospital care is proportionally less than in previous surges.
Official data shows that 7.5% of Spanish hospital beds and 18% of intensive care units are treating COVID-19 patients. Authorities reported 120 new deaths since Dec. 23.
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.
