While there has been an increase in COVID vaccinations, a number of studies and the rapid spread of coronavirus variations have verified our fears: vaccine-induced immunity may not be as long-lasting as we thought.
Vaccines have been clinically evaluated and confirmed to lessen illness transmission and severity, but their immune defenses might wane with time, making a person vulnerable to dangers once again. Antibody testing has risen as a result, with many people who have been completely vaccinated choosing for the tests to determine their risks. But when is the right time to go for it? If that's the case, how accurate are the readings?
What is antibody testing and how do they work?
The IgG and IgM proteins produced by the immune system are determined by antibody or serology testing. In a sense, they also determine an individual's level of protective immunity, and so provide a tool for people to assess their level of protection and determine if the vaccination is doing its work properly.
How quickly do antibodies deteriorate after a COVID vaccination?
While vaccinations do not provide a complete cure, they do help to minimize the chances of infection, sickness severity, and transmission for a long time—as long as the immune protection lasts. Despite all of the benefits, immunizations do not truly protect us for a lifetime.
According to multiple studies and clinical data, vaccine-induced immunity, which is distinct from natural immunity, can begin to decline 90-120 days following full immunization, meaning that a person who has reached peak immunity begins to experience diminishing antibody counts months after vaccination. The dip can also be exacerbated by variants such as the Delta variant, which can easily cause the dip.
Some vaccines are more susceptible to waning immunity than others. As is clear, certain vaccines are better than others at eliciting a larger, stronger, or longer-lasting antibody response, therefore the drop in immunity may be more pronounced with some vaccines.
Who is in danger? Who should get the tests done?
While there are strong signs of a third wave on the way, getting an antibody test now, especially weeks (or months) after full vaccination, can be a really effective approach if you find yourself at a higher risk.
Even though there isn't much a fully vaccinated person can do at this point (aside from taking extra precautions) without the availability of booster shots, finding out the results of an antibody test could help identify who may be at a higher risk than others, or who may require additional protection, despite having received both vaccine shots. The tests may be able to identify and estimate the further preventive measures that may be required.
There may also be persons who benefit from having an antibody test done many weeks after immunization. Immunocompromised patients, particularly those with significant comorbidities, may not be able to build needed antibodies after vaccination, or have a rapid fall in their immunity levels, according to studies. Obtaining an antibody test at the appropriate time could assist in determining whether the vaccine is effective in delivering the necessary protection against coronavirus and its variations.
Even though an antibody test isn't required for everyone, some groups, such as the immunocompromised, those with weakened immunity, covid warriors or those with preconditions may benefit from getting a test done at some point post-vaccination and know about their risks beforehand.
