According to an Omicron expert Dr John Campbell, most will have the
natural immunity (listen around 17:45 seconds)against Covid soon. The pandemic will become endemic by Spring (April/May 2022?) and life will go on as normal.
The UK government has allowed vaccinated visitors from other countries to enter UK without testing or quarantined from Feb this year (next month). Also wearing of face masks and social distancing will not be compulsory.
Hopefully, SG will follow UK and allow visitors into the country. Businesses and travels will resume once again. SIA will start being profitable again.
Looking forward to the weakening if not the demise of the coronavirus!
