I know lots of people who take a 'flu booster every year ..... Always assumed covid would be the same.

For covid shots it is not once a year but I think once every 3 to 6 months and certainly not more than 6 months.

Are you up to date on your adult vaccination schedule?
Why do you feel the need to take the flu shot when it is absolutely useless?

Flu shots are 40 to 60% effective. How is that useless?
This study qualitatively and quantitatively analyzes the role of seasonality in the spread of COVID-19. We find that COVID-19 infectivity and mortality of SARS-CoV-2 are both stronger in colder climates, and COVID-19 seasonality is more pronounced at higher latitudes. Numerical simulation indicates that seasonality alone is not sufficient to stop the virus transmission in the warm season, but it should be taken into account in the future planning of intervention measures. Our findings have important implications in the control and prevention of COVID-19. Rational policy planning aggregated with beneficial effects of seasonal variation may provide a window of opportunity to expand healthcare capacities and develop effective and safe pharmacological treatments. In winter months, cases of COVID-19 may surge along with other coronaviruses’ infections and seasonal influenza, which would trigger a substantial increase in the demand for healthcare system resources. Although vaccines have streamed into communities to protect people against coronavirus, scientists warn that herd immunity to the COVID-19 is not likely to be achieved in 2021 (VOA News, 2021).
The roles of climate and true seasonal signatures in the epidemiology of emergent pathogens, and that of SARS-CoV-2 in particular, remain poorly understood. With a statistical method designed to detect transitory associations, we show, for COVID-19 cases, strong consistent negative effects of both temperature and absolute humidity at large spatial scales. At finer spatial resolutions, we substantiate these connections during the seasonal rise and fall of COVID-19. Strong disease responses are identified in the first two waves, suggesting clear ranges for temperature and absolute humidity that are similar to those formerly described for seasonal influenza. For COVID-19, in all studied regions and pandemic waves, a process-based model that incorporates a temperature-dependent transmission rate outperforms baseline formulations with no driver or a sinusoidal seasonality. Our results, so far, classify COVID-19 as a seasonal low-temperature infection and suggest an important contribution of the airborne pathway in the transmission of SARS-CoV-2, with implications for the control measures we discuss.
