Could COVID-19 be behind the rise in rare and aggressive cancers?
Since the pandemic, there has been a rise in new cancer cases, including rare and aggressive, late-stage cancers — and some physicians and researchers believe that COVID-19 may be behind this increase. Here's what you need to know.
Still No Evidence COVID-19 Vaccination Increases Cancer Risk, Despite Posts - FactCheck.org
It has not been shown that COVID-19 vaccines cause or accelerate cancer. Yet opponents of the vaccines say a new review article “has found that COVID-19 mRNA vaccines could aid cancer development.” The review conclusions are mainly based on the misinterpretation of a study on mRNA cancer vaccines in mice.

COVID-19 and pregnancy: a comprehensive study of comorbidities and outcomes - BMC Public Health
Objectives This study aimed to investigate the impact of pregnancy and pre-existing comorbidities on COVID-19 infections and associated complications of hospitalisation and mortality in women of reproductive age (WRA). The study also compared the risk of severe COVID-19 complications between pregnant women (PW) and non-pregnant women (NPW) with and without pre-existing comorbidities. Special focus was placed on some understudied comorbidities of immunosuppression, chronic renal disease and chronic obstructive pulmonary disease (COPD). Methods The study utilized anonymized patient-related information for a population of 7,342,869 WRA from the Mexican Ministry of Health data repository on COVID-19. Descriptive variables were characterized using frequencies, percentages, means, and standard deviations. Adjusted odds ratios (aORs) were used to assess the associations between risk factors and outcomes of hospitalisation and mortality. The study covered the entire COVID-19 pandemic period from January 30, 2020, to May 5, 2023. Results The findings revealed that PW were not more likely to get COVID-19 infections than NPW. PW with COVID-19 infections were more likely to require hospital admission, intubation treatments, and ICU admission compared to NPW with COVID-19. PW with immunosuppression had an increased odds ratio (aOR) of getting COVID-19 infections compared to NPW (PW: aOR = 1.0396; NPW: aOR = 0.8373). NPW with immunosuppression had higher risk of mortality (all-cause death: aOR = 1.7084; COVID-19-associated death: aOR = 1.4079) and hospitalisation (all-cause hospitalisation: aOR = 4.1328; COVID-19-associated hospitalisation: aOR = 3.0451) than NPW without immunosuppression. Renal disease was identified as a concerning pre-existing condition that increased the risks of COVID-19 associated mortality/hospitalizations and all-cause mortality/hospitalizations for both PW and NPW. NPW with renal disease had much higher odds ratio (aOR) of either COVID-19-associated-hospitalisations (NPW: aOR = 8.639; PW: aOR = 1.7603) or all-cause hospitalisations (NPW: aOR = 8.8594; PW: aOR = 1.786) than PW with renal disease. Conclusions This study provides valuable insights into the impact of pregnancy and pre-existing comorbidities on COVID-19 outcomes in WRA. The findings underscore the importance of considering demographic factors and pre-existing comorbidities in the management of PW with COVID-19. The study also highlights the need for further research to understand the unique impacts of different comorbidities, particularly immunosuppression and renal disease, on COVID-19 outcomes in WRA.
COVID-19 during pregnancy means 10 times higher risk of ICU admission, Canadian data suggests
Canadian data suggests people who are pregnant face significantly higher risks of serious COVID-19 requiring hospitalization, ICU admission, or life support — a particular concern because pregnant people tend to have lower rates of vaccination.
Since first being identified in December 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as an etiological agent behind Coronavirus disease 19 (COVID-19), has caused three waves of a global pandemic, with a fourth in progress. ...

Flawed Analysis of New Zealand Data Doesn’t Show COVID-19 Vaccines Killed Millions - FactCheck.org
Data from around the world support the general safety of the COVID-19 vaccines. Some people online, however, incorrectly claim that illegally obtained data from New Zealand show the vaccines have killed 13 million people worldwide. Experts say the analysis is bogus.
American vaccine disinformation used as ‘Trojan horse’ for far right in New Zealand

“They wanted to, but they just couldn’t get there”: GBA + implementation and gaps during the COVID-19 pandemic in Canada - International Journal for Equity in Health
Purpose To improve understanding of the barriers and enablers to implementing gender and intersectional analysis during the COVID-19 pandemic in Canada. Methods We conducted a policy document analysis (n = 70) of equity-focused policies of the Canadian government published between March 2020 and August 2023. This analysis was complemented with 16 semi-structured key informant interviews with federal policy actors and leadership of civil society organizations. Results Pandemic policy documents demonstrated multiple commitments to address pandemic related inequities, with key informants describing collaborative approaches to implementing these policies, but also limits in terms of the urgent and diffused nature of pandemic response. Implementation gaps related to accessible information, health services and vaccinations were noted and attributed to a reliance on civil society actors who lacked sufficient and sustainable resources, and the behaviors of priority populations whose capacity to comply was limited by the same inequities the policies sought to address. Conclusion The Canadian federal government made concerted efforts to address the needs of a range of priority populations and equity issue areas within its pandemic response, with mixed results. Having a pre-established framework to guide implementation and related relationships overcame some of the urgency challenges related with pandemic response. However, implementation gaps reflected preexisting inequities shaped by broader economic, social and political systems which were infrequently addressed in pandemic policies. There is a need for greater understanding of policy implementation gaps during emergency and crisis response.
How Canada’s decentralised covid-19 response affected public health data and decision making
Tania Bubela and colleagues examine how fragmented responsibilities and accountability for public health data hindered Canada’s pandemic response
Canada’s public health system was reformed after its 2003 severe acute respiratory syndrome (SARS) outbreak, which was the worst outside of Asia with 438 cases and 44 deaths.1 Ensuing national and provincial inquiries led to the creation of the national Public Health Agency of Canada (PHAC) to coordinate Canada’s preparation for and response to public health threats.2 Subnational public health agencies were also created or strengthened to function as regional centres for disease control.1 These actions should have put Canada in a good position to respond to the covid-19 pandemic.34
Despite these reforms, Canada experienced serious failures during the covid-19 pandemic. Memories faded rapidly after SARS, and if history is not to repeat itself, government and health system leaders must strengthen the country’s public health and healthcare systems in preparation for the next threat. Health authorities as well as all Canadians need to reflect on the crises of the past three years—what went well and why; what caused pandemic response failures, and what were their consequences? Here, in the first of a series of articles examining Canada’s response and setting out suggestions for a national inquiry, we examine the limitations of the country’s decentralised structure for public health decision making and missed lessons from the 2003 SARS-CoV-1 outbreak, particularly with regard to data infrastructure.5 Other articles in the series examine how research and data failed to inform public health responses tailored to community and population needs,6 the predictable failures in long term care,7 and Canada’s role in global vaccine inequity.8
