Vaccines Act Against Infection, The Severe Covid-19 Disease, Study Reveals |  India News


NEW DELHI: Christian Medicine SchoolVellore, a 2,600-bed tertiary care hospital in India with 10,600 employees has vaccinated 84.8 percent of staff, most of them receiving Covishield and receiving rest. Covaxin for Bharat Biotech, revealed more recent research conducted on healthcare workers.
“Christian Medical College, Vellore, a 2,600-bed tertiary care hospital in India with 10,600 employees, vaccinated 8,991 employees (84.8%) between January 21 and April 30. The majority (93.4% ) received Covishield, the Oxford-AstraZeneca vaccine manufactured by Serum Institute of India, and the rest, Covaxin, a killed virus vaccine, produced by Bharat Biotech, India, “the study said,” The vaccines work against infection and severe disease from Covid-19, “by CMC Vellore.
Dr. Joy J Mammen, Professor, Department of Transfusion Medicine, CMC Vellore is the corresponding author of the preprint study.
“We report the incidence of symptomatic Covid-19 infection among healthcare workers between February 21 and May 19. In the 1,350 employees who tested positive for RT-PCR, the median age (interquartile range) was 33 years (27-41); women: men The ratio was 3: 2. The mean time from the first dose to the development of the infection was 77 (62-89) days and coincided with the second peak in India during April and May 2021, “the study said.
“Vaccines are working! Good against infections (in healthcare = high transmission), great against serious diseases. Here is the first data from healthcare workers at the Medical College, Vellore, led by Joy Mammen, “tweeted Dr. Gagandeep Kang, professor at CMC Vellore.
This research was previously peer-reviewed and it was found that 33 healthcare workers (HCWs) developed the infection within two weeks after the second dose of the vaccine. Among fully vaccinated healthcare workers (n = 7080), 679 (9.6%) developed the infection 47 days (34-58) after the second dose.
But the risk of infection among fully vaccinated healthcare workers was lower compared to those who were not vaccinated. The study said that “the risk of infection among fully vaccinated healthcare workers was significantly lower compared to unvaccinated healthcare workers (relative risk (RR) 0.35, 95% confidence interval (CI) 0.32- 0.39) “.
Health workers who were fully vaccinated required less hospitalization, oxygen therapy, and even admission to the ICU.
“Similarly, two-dose vaccination reduced hospitalization (RR 0.23, 95% CI 0.16-0.32), the need for oxygen therapy (RR 0.08, 95% CI 0, 03-0.26) and admission to the ICU (RR 0.06; 95% CI: 0.01-0.27). The protective effect of vaccination in the prevention of infections, hospitalization, need for oxygen and ICU admission was 65%, 77%, 92% and 94%, respectively. ”
“The only staff member who died since the beginning of the pandemic had multiple comorbidities and had not received the vaccine. Subgroup analysis of the efficacy of the two vaccines was not possible because few healthcare workers received Covaxin. Some healthcare workers (17%) could not take the second dose, initially due to a shortage of vaccines and later despite the availability of vaccines, due to changes in the guidelines on the interval between doses, ”the study reported.
There are many other studies done by other countries that show that vaccination protects.
A study of 23,324 healthcare workers in the UK reported vaccine coverage to be 89 percent. During the two-month follow-up, symptomatic and asymptomatic infections occurred in 80 participants (3.8%) among the vaccinated and 977 (38%) among the unvaccinated.
In a study of Jerusalem, the infection occurred for two months in 366 (6.9 percent) of 5,297 vaccinated healthcare workers and in 213 of 754 unvaccinated people. A third study from California (n = 28,184) showed that only 37 TSs who received two doses of the vaccine tested positive.
It stated: “Our study corroborates these studies that vaccination is protective, although we did not analyze the variants responsible for the second massive wave. Beyond the immediate, the implications for public health include cost-effective protection against infection, reduction of severity of the disease and an intervention to effectively break the chain of transmission.Even when many states chose to restrict movement to reduce stress on the healthcare system, we realize that future waves, at best cases, they can be prevented or, in the worst case, mitigated by aggressive and widespread vaccination. ”
