Daily US Times: Data from England suggests that people are twice as likely to need hospital care if they are sick with the Delta variant of covid-19, rather than the Alpha variant that was once prevalent in the United Kingdom.
Experts say the big study reinforces why it is important that people get fully jabbed. The study was published in The Lancet.
Vaccination cuts the risk of serious illness from either variant of Covid-19, although Delta is the current threat.
Currently, Delta variant accounts for almost all UK cases.
The study looked at 43,338 Covid cases that occurred between March and May – when both Alpha, also known as Kent, variant, and Delta were circulating in the UK. The study was led by Public Health England (PHE) and the Medical Research Council.
The bulk of these coronavirus cases were in people who had not yet been vaccinated.
Most didn’t need hospital care, but a small proportion – 196 (2.3%) of the people infected with Delta variant and 764 (2.2%) of those with Alpha variant – did.
Risk of hospitalization was twice as high for individuals diagnosed with the Delta variant, compared to those with Alpha, after adjusting for differences such as sex, age and ethnicity.
Experts say being vaccinated should bring down this risk and both doses are needed for maximum protection.
A recent analysis by PHE suggests that effectiveness against hospitalization after two doses is:
92% for the Oxford-AstraZeneca vaccine
96% for the Pfizer-BioNTech vaccine
