If you're getting the two-dose Pfizer Covid-19 vaccine, you’ll need to receive your first jab this week to be protected in time for Christmas.
that a single dose of Comirnaty's vaccine protects only modestly against infection and mild Covid, especially with the highly infectious Delta variant, but that it still works quite well in protecting against severe disease. Two doses, however, provide the best immunity as the second one reinforces the body’s immune response.
What about the J&J vaccine?The J&J vaccine requires only one dose. If you receive this vaccine, you are considered fully vaccinated (protected) two weeks after your shot. Protecting yourself as well as othersVaccination not only protects the individual, but also those around them. Evidence indicates that vaccinated individuals are less likely to transmit the virus.
While a vaccinated person may have the same viral load (the amount of virus in a person’s body) as an unvaccinated person, the duration of viral shedding – when a virus is released from the infected host – and the type of symptoms the vaccinated individual displays are much less than in unvaccinated individuals, Madhi recently said. This has been seen with both the J&J and Comirnaty vaccines. headtopics.com
What if I’ve had a natural infection?Calculations by Discovery Health indicated that 80% of South Africans may already have contracted the virus during the past three waves, and immunity derived through natural infection cannot be overlooked, Madhi stressed.
“If you had a past infection and get a single dose of the vaccine, you'll get a tremendous immune response,” he said but added that this comes at a cost.“People who want to gain immunity through natural infection do so at a risk of ending up in hospital, dying, and developing long Covid,” he added.
Madhi also previously explained that natural infection induces a less predictable antibody response compared to vaccination. Natural immunity may also vary from person to person.Predicted fourth waveLocal experts have stated that South Africa is likely to experience a fourth wave of Covid cases as early as December 2021, although its severity cannot be predicted.
“I think it’s possibly going to be different but we don’t really know,” Professor Adrian Puren, Acting Executive Director of the National Institute for Communicable Diseases (NICD), said in September.The factors that need to be taken into account is that although South Africa has a large proportion of individuals that have experienced natural infection, and vaccine rollouts are in place, there is still a significant number of people that have not been exposed to the virus, highlighting the need for greater vaccination uptake. headtopics.com
“Vaccines do work. They are effective. It will happen that vaccinated individuals end up in the hospital wards, but not to the same extent as individuals who are unvaccinated,” said Puren. Vaccination uptake among older age groupsMadhi also expressed concern about the low vaccine uptake among the older age groups, who are at greatest risk of Covid-related severe illness or death.
Earlier this month, stats revealed that about 50% of people between 50 and 59 years and around 60% of people above the age of 60 years have been vaccinated, but that figure needed to increase to roughly 85 to 90% of people above the age of 50, Madhi said.
“If we’re able to do that, even when we experience a resurgence, what won’t occur is an overwhelming of our healthcare facilities,” he explained.The South African government aims to have given at least one dose of the vaccine to 35 million of its 60 million people by Christmas, acting director-general (DG) of the health department, Dr Nicholas Crisp,
saidin July this year.As of 26 October 2021, just over 21.7 million doses of the vaccines had been administered in the country. Read more: News24 »
