Covid-19 claims 52 lives in Pakistan while 1,560 positive cases emerge
Covid-19 has claimed 52 lives in 24 hours while 1,560 positive cases reported in Pakistan, according to National Command and Operation Centre (NCOC).
Total 48,836 tests were conducted in the last 24 hours as the positivity percentage was measured at 3.19%.
The country is facing 4th wave of the coronavirus and it has so far reported 1,243,385 cases and 27,690 deaths since the beginning of pandemic.
Yesterday, Pakistan reported 1,400 positive cases of covid-19 with 41 deaths .
Does having no side effects from the Covid-19 vaccine guarantee immunity?
People around the world have taken the Covid-19 vaccine, but their concern regarding its effectiveness continues to bring forth various queries.
A prominent query is about the link between the side effects after injecting the vaccine and the immunity gained by it.
Presently, there are 21 COVID-19 vaccines approved for application across the globe. According to the data compiled by Google, over 13 percent of the total population globally has been vaccinated.
A trusted source of The Centers for Disease Control and Prevention (CDC) states that all vaccines are being safely monitored and administered across the world, and the Health authorities worldwide encourage citizens who get a vaccine to report all side effects.
Some of the most common vaccine side effects include swelling, redness, pain at the injection site, fever, headache, tiredness, muscle pain, chills, and nausea.
Side effects are observed in any case with any type of vaccine, however, each individual reacts differently depending on his or her immune response.
There are multiple reports of people not feeling any side effects. Does this make the vaccines less effective?

‘No straight link of side effects and protection’
William Schaffner, M.D., a professor of infectious diseases at Vanderbilt University Medical Center in Nashville, TN, gave an interview associated with the Medical News Today and talked about the relationship between side effects and immunity to SARS-CoV-2, the virus that induces COVID-19.
Schaffner has stated that neither the appearance nor the lack of side effects displays immunity.
Data gathered from the trials of the two-dose mRNA COVID-19 vaccines Pfizer-BioNTech and Moderna has verified that the vaccines are 90% effective. Beneath 10% of the people who are fully vaccinated might have partial to zero protection.
Vaccines work by inciting the body to produce antibodies to target the relevant pathogens. People with compromised immune systems are more likely to build up total or even partial protection to SARS-CoV-2.
Schaffner concludes that some medications like immunosuppressants and certain drugs used in cancer treatments may also negatively influence the effectiveness of COVID-19 vaccines.
The importance of antibody testing
Scientists have proposed that antibody testing can better evaluate whether a COVID-19 vaccine has developed immunity to the new coronavirus.
Nevertheless, The Food and Drug Administration (FDA) has lately published a statement stating that “antibody tests should not be used to evaluate a person’s level of immunity or protection from COVID-19 when detected positive at any time, and especially after the person received a COVID-19 vaccination.”
Antibody testing can seem like a sensible way to conclude whether a person has produced antibodies to SARS-CoV-2, but a positive test result does not surely mean that the individual will not develop COVID-19.
The FDA also adds that this information can lead to people having a more relaxed attitude against the spreading of the virus and can ultimately increase the number of infected.
Dr. Elitza S. Theel, the director of the Infectious Diseases Serology Laboratory at the Mayo Clinic in Rochester, says “There is not yet an established correlate of immunity for SARS-CoV-2 like we have for other vaccine-preventable diseases.”
Theel also states that the available COVID-19 serologic tests were not created to show the immunization against the virus, but to register whether the person’s body has reacted to it or not.
It is recorded that the body is fully able to build protection after the vaccines in 2 weeks following the second dose of the Pfizer-BioNTech or Moderna vaccines and 2 weeks following the single dose of Johnson & Johnson, or Janssen.
According to Dr. Theel, “The current surge in [COVID-19] cases is primarily occurring in unvaccinated individuals, which is both heartbreaking and frustrating because these could have been largely prevented had those individuals opted to get vaccinated.
