Hong Kong’s high death rate shows the importance of vaccinating the elderly.

As the death toll from Covid-19 in Hong Kong rises. Some scientists have said that vaccinating as many older people as possible should be a top priority in the Omicron era. Hong Kong, which was once one of the world’s most formidable “Covid zero” redoubts. They have offered scientists a case study on the threat posed by Omicron in a very different place. The dense city where people can not be unaffected by previous infections. But also and were the oldest and most vulnerable residents were largely unvaccinated.

According to health experts, several important lessons have been learned.

Omicron sub-variants circulate

.The scientists said vaccination of the general population remains essential. But vaccinating as many older people as possible has become the most critical task.

The message was most relevant to China. They said that vaccination in older age groups is also lagging and that immunity from earlier infections is weak.

But it was again confirmed in the United States. Low vaccination and booster rates among the elderly have led scientists to worry about a potential spike in BA.2 cases. Scholars do not expect the United States to face the same dire situation as Hong Kong in the coming months. Many more Americans have been infected and killed during previous waves by the coronavirus.

Hong Kong, along with mainland China was one of the latest opponents of a strategy of tight restrictions and border controls to eradicate the virus. Found itself vulnerable due to how few of its residents had any immunity from previous infections. Before the Omicron surge, scientists estimated that only 1 percent of Hong Kong’s population had contracted the virus.

Less than a quarter of people aged 80 and over in Hong Kong received two doses of the vaccine before the Omicron spike. They were compared to more than 90 percent of Singapore and New Zealand people.

The city currently has 39 percent of residents aged 80 and over-vaccinated, although nearly two-thirds of children aged 12 to 19 have been vaccinated.
