The #COVID19 Vaccine is Strongly Encouraged for Pregnant Persons. Here’s why it’s REALLY important 🧵

1⃣ Pregnancy is associated with elevated risk of severe illness
2⃣ The vaccine is safe and does NOT raise risk of miscarriage
3⃣ The vaccine protects mothers and their babies
1⃣ Pregnant persons are at greater risk of severe illness from COVID-19. This meta-analysis demonstrated that, when compared to non-pregnant reproductive aged women, pregnant persons were more likely to be admitted to the ICU and require ventilation

1⃣ Pregnant persons with COVID-19 are also more likely to deliver preterm, can have increased risk of maternal death, and their babies are more likely to be admitted to the neonatal intensive care unit when compared to those pregnant without COVID-19

THREAD: You may have seen a manuscript which was released yesterday on Vitamin D levels and #COVID19. Here is some quick commentary on the paper 1/
The article assessed differences in 25-hydroxyvitamin D (25OHD) levels in hospitalized patients with COVID-19 v.s. population-based controls.

Statistically significant differences were found in 25OHD levels b/w groups BUT not in disease severity

Link: academic.oup.com/jcem/advance-a… 2/
Findings (mean±SD):

Hospitalized COVID-19 patients:
👉 13.8±7.2 ng/ml (25OHD)

Population-based controls:
👉 20.9±7.4 ng/ml (25OHD)

So what does this mean? 3/

I believe that many sentiments, which have recently been put forth, regarding Sweden’s approach to #COVID19 overlook a critical metric. I would like to discuss some of my thoughts.

Preface: this thread was not created to favour one country’s response over another’s; nor do I have evidence to substantiate a definitive conclusion

It is merely to suggest other factors which should be considered when evaluating a response's success

Please keep this in mind 2/
A pandemic’s ‘health footprint’ illustrates the summation of direct & indirect implications on a country’s overall health

This concept may be modelled by 4 distinct curves demonstrating each wave’s respective magnitude

Over 60 million Italian citizens under lockdown as #Coronavirus incidences surge. Over 9000 confirmed cases in Italy & rising.

The unfortunate consequence are the associated ethical concerns regarding resource allocation.

Incessant rising in cases warrants the question: are hospitals prepared for the associated influx of patients?

Further admissions require beds, PPE, ventilators, staff etc. What happens when resources run out, ventilators are all in use, or there aren’t enough staff?

2/5
Ultimately, scarcity of medical resources may pressure healthcare practitioners to decide who receives care. This is NOT a question anyone should ever have to answer.

Resources should never be the limiting factor of care
