Though vaccination is the key to containing the spread of the Covid -19 pandemic and prevent severe illness or death, it appears that vaccines are not 100% effective at preventing infection as people who are fully vaccinated will still get covid-19.
There is a growing concern that vaccinated people may be more vulnerable to serious illness than previously thought and the dearth of scientific studies in the matter has left the public policymakers and corporate executives to draft broken plans.
In the absence of clear public health messaging, people once vaccinated are now left abandoned and uninformed. It takes to the very bottom of hardship not just for the officials to decide on booster shots but to recheck the schedules if things have been mitigated.
Resorting to case studies also does little help as it serves dissimilar results. Apparently, the surveys ripple in different directions, further providing incomparable images.
Better confidence in vaccinated people has also paved the way for more tragedy. One of the best-known outbreaks among vaccinated people occurred in the small beach town of Provincetown, Massachusetts, as thousands of vaccinated and unvaccinated alike gathered on dance floors and at house parties over the Fourth of July weekend to celebrate the holiday -- and what seemed like a turning point in the pandemic. About three-fourths of the 469 infections were among vaccinated people.
It generate great concern when authors of a CDC case study noted the chances of them just likely to transmit Covid-19 as the unvaccinated. The incident prompted the CDC to reverse a recommendation it had issued just a few weeks earlier and once again urge the vaccinated to mask up in certain settings.
Another incident in Colorado also calls for better precautions as it was found that the breakthrough infection rate in one county, Mesa, was significantly higher than the rest of the state, at 7% versus about 5%.
The report suggested it was perhaps because the delta variant was circulating more widely there, but also noted the ages of patients in Mesa and the lower vaccination rate may have played a role.
Results from Israel and the US also suggests that some people will need booster shots in the coming months to contain the infection. However, it has now become difficult to state decline immunity or vaccination that are inefficient to deal with delta variant is to be blamed for the virus spread.
Hence, though vaccines provide significant protection against the virus, it certainly does not make it an absolute solution to host gatherings with no restrictions as it is common for viral immunity to naturally decline over time.
