As the world struggles to develop a drug that could eliminate Covid-19, a new study has said that vaccines that are currently available cut the risk of transmission significantly. A study conducted by the Public Health England (PHE) said that a single dose of a Pfizer or AstraZeneca vaccine against the virus reduces the chance of transmission by 50 percent. Pfizer and AstraZeneca are two among others that are being currently administered to people around the world. The study noted that people inoculated with the first jab of either Pfizer or AstraZeneca didn’t become a carrier of the virus. It said that protection against the virus was seen 14 days after inoculation.
38 percent of those inoculated with the first dose of Pfizer, cut the risk of spread to unvaccinated people. Those vaccinated with AstraZeneca cut the transmission by 49 percent. The findings suggest similar levels of protection were developed after two weeks. The PHE added that this is regardless of age and cases. Besides, those vaccinated with the first dose also showed a reduced risk of developing an asymptomatic infection after four weeks. The risk was reduced by almost 65 percent. The study noted that vaccines against Covid-19 are vital in the fight against the deadly virus. Vaccinating maximum people as early as possible will help in returning to normal.
Scientists have said that vaccines reduce the severity of Covid-19. Also, these drugs prevent deaths from the virus. Countries like the US and the UK have managed to bring the Covid-19 situation under control by vaccinating their population. Vaccines have an additional benefit that they also cut the chance of passing the infection to others. The PHE study involved 57,000 contacts from 24,000 households. These households had a lab-confirmed case of infection after receiving a vaccine. The findings assume significance as people still fear that the drugs are not effective and are avoiding taking jabs. It added that people should take the vaccine and also follow the Covid appropriate behaviors.
