Suara.com – Since its initial appearance at the end of December 2019, the corona virus that causes COVID-19 has mutated dozens of times. However, until the second year the Covid-19 pandemic occurred, the various variants of the SARS Cov-2 corona virus had not yet shown signs of weakening.
It is also recognized by an epidemiologist from Griffith University Australia, dr. Dicky Budiman. Contacted Suara.com some time ago, Dicky said how the corona virus had not weakened.
“In my opinion, currently there is no visible weakening. Therefore, it needs to continue to be researched, because mutations often occur, even omicron is not the last,” he said.
Symptoms caused by Omicron are mild compared to the previous variant. However, according to Dicky, this does not mean that the mutation of the corona virus has weakened.

However, it is precisely because of the role of vaccination that many people already have antibodies. Thus, herd immunity began to form in society. Even so, the achievement of herd immunity is also not on target. Or even difficult to achieve.
“Currently, herd immunity is not very logical to achieve because this coronavirus continues to mutate. In addition, the intervention response is still weak in many countries, and has not shown a decline (positive cases) in the last 2 years,” he explained.
The second reason for herd immunity is that it is difficult to achieve the target because the antibodies actually do not last long. Provisional research results show that antibodies last no more than 7 months.
The third reason is the fact that the current Covid-19 vaccine is effective but cannot prevent infection 100 percent.
“Then the last thing, the fact that (Covid-19) is a zoonotic virus where the reservoir or host is naturally in wild animals. This means that it will continue to mutate in wild animals or from humans to animals, animals to humans,” he explained.

Even though in the end the world’s herd immunity can reach the target, the risk of the emergence of a Covid-19 mutation will always exist, said doctor Dicky. Because the virus is also able to reproduce in the body of animals.
