COVID-19 vaccine: Why you need it even after contracting the virus

Experts say that those who have had the coronavirus should still obtain COVID-19 vaccination doses.

COVID-19 vaccination apprehension persists in many regions of the world. Despite all of the experts’ guarantees and advice, a sizable minority of people continue to refuse the vaccine.

Despite this, health officials continue to remind and push the people to acquire vaccines. This is true even for people who have previously been exposed to the coronavirus.

Healthline recently released a report, explaining why even those who contracted the virus need to take the jabs. As noted, these individuals may still experience reinfection, and consequently, transmit it to others.

Why COVID-19 vaccine is a need

According to the journal, the Centers for Disease Control and Prevention has provided guidelines on the subject. According to the official website, “experts do not yet know how long” the protection will persist following recovery from the coronavirus.

It also points out that reinfection, “although rare,” is possible. This is why getting a COVID-19 vaccine is necessary.

An infectious disease expert at Vanderbilt University shared some pointers about the guidance. He said that the recommendation is “based on two factors.”

Dr. William Schaffner explained that the “antibody levels after vaccination are much higher” than the levels after natural infection. He, then, added that higher antibody levels usually have links to a much “longer duration of protection.”

The expert, later on, referenced “Tony Fauci’s word” to point out the second factor. He said that “higher antibody levels provide a greater cushion of protection against some of the variants.”

The cause for another reminder

The latest recommendations and reminders from experts reportedly come after Senator Rand Paul of Kentucky stated that he does not have plans on getting a COVID-19 vaccine. The same publication said that he contracted the virus earlier in March 2020.

Speaking to a WABC radio show in New York, he noted that he made his “own personal decision” not to get the vaccine because he has already had the disease. Accordingly, he concludes that he has “natural immunity.”

In reaction to the senator’s statements, Dr. Julie Parsonnet saw them as evidence of a “lack of understanding” about how immunity works. While she accepted that there will be “some immunity” after encountering the virus, she believes that receiving a COVID-19 vaccination will give “better immunity.”

For the sake of possible long-term immunity

Meanwhile, according to Khou, researchers discovered that persons who have COVID-19 and received immunizations may have long-lasting protection. This comes as talks concerning booster injections have continued to arise in recent weeks.


As noted, the studies reportedly show the immune response due to a previous contraction, alongside a COVID-19 vaccine, “is so strong that it can fight” COVID-19 variants. This does not apply, however, to those who just had their vaccines and to those who recovered from the virus but did not get the jab.
