Safety and efficacy of vaccinations during pregnancy have been a matter of debate. In the aftermath of the 2009 H1N1 influenza pandemic, a growing body of research has emerged, which points toward the importance of adhering to influenza vaccination recommendations for pregnant women. The same applies for vaccination against pertussis. Some vaccines (e.g., live attenuated) are still contraindicated during pregnancy. However, data indicate that these vaccines do not result in fetal impairment when administered accidentally during pregnancy. In the following, we provide a review on vaccination-related safety and efficacy aspects in pregnant women, shedding some light on potential barriers that stymie vaccination uptake among pregnant women and introducing strategies to overcome these barriers.

AbstractThe COVID-19 outbreak is increasing around the world in the number of cases, deaths, and affected countries. Currently, the knowledge regarding the clinical impact of COVID-19 on maternal, fetal, and placental aspects of pregnancy is minimal. Although the elderly and men were the most affected population, in previous situations, such as the 2009 H1N1 influenza pandemic and the Ebola epidemic, pregnant women were more likely to develop complications than nonpregnant women. There are unanswered questions specific to pregnant women, such as whether pregnant women are more severely affected and whether intrauterine transmission occurs. Additional information is needed to inform key decisions, such as whether pregnant health care workers should receive special consideration, whether to separate infected mothers and their newborns, and whether it is safe for infected women to breastfeed.

Asia is considered an important source of influenza A virus (IAV) pandemics, owing to large, diverse viral reservoirs in poultry and swine. However, the zoonotic origins of the 2009 A/H1N1 influenza pandemic virus (pdmH1N1) remain unclear, due to conflicting evidence from swine and humans. There is strong evidence that the first human outbreak of pdmH1N1 occurred in Mexico in early 2009. However, no related swine viruses have been detected in Mexico or any part of the Americas, and to date the most closely related ancestor viruses were identified in Asian swine. Here, we use 58 new whole-genome sequences from IAVs collected in Mexican swine to establish that the swine virus responsible for the 2009 pandemic evolved in central Mexico. This finding highlights how the 2009 pandemic arose from a region not considered a pandemic risk, owing to an expansion of IAV diversity in swine resulting from long-distance live swine trade.
