RESUMEN
OBJECTIVE: We provide an overview of the safety of messenger RNA and inactivated coronavirus disease 2019 (COVID-19) vaccine and monitoring of pregnant women after COVID-19 vaccination. The vaccine safety outcome profile is beneficial for further recommendations of COVID-19 vaccination in pregnancy. METHODS: This research was conducted as descriptive research. Sampling was performed using an online questionnaire to be filled out voluntarily and distributed to all pregnant women in Indonesia who received the COVID-19 vaccination. Data collection was performed and descriptive statistics were obtained. RESULTS: Among 31 977 pregnant women, 24 212 (75.7%) received the first dose, 7619 (23.8%) received the second dose, and 146 (4.5%) received the third dose of the COVID-19 vaccine. Sinovac vaccine is the most administered vaccine to pregnant women (27 122 [84%]). Most pregnant women (78.7%) who were vaccinated had no adverse effects after immunization, while the most reported adverse effects were mild symptoms. CONCLUSION: The current study contributed evidence that COVID-19 vaccination during pregnancy has minimal adverse effects. These findings may help pregnant women and healthcare providers to make informed decisions regarding vaccination.

Time-lapse resistivity measurements and groundwater geochemistry were used to study salinity effect on groundwater aquifer at the ex-promontory-land of Carey Island in Malaysia. Resistivity was measured by ABEM Terrameter SAS4000 and ES10-64 electrode selector. Relationship between earth resistivity and total dissolved solids (TDS) was derived, and with resistivity images, used to identify water types: fresh (ρ ( e ) > 6.5 Ω m), brackish (3 Ω m < ρ ( e ) < 6.5 Ω m), or saline (ρ ( e ) < 3 Ω m). Long-term monitoring of the studied area's groundwater quality via measurements of its time-lapse resistivity showed salinity changes in the island's groundwater aquifers not conforming to seawater-freshwater hydraulic gradient. In some aquifers far from the coast, saline water was dominant, while in some others, freshwater 30 m thick showed groundwater potential. Land transformation is believed to have changed the island's hydrogeology, which receives saltwater pressure all the time, limiting freshwater recharge to the groundwater system. The time-lapse resistivity measurements showed active salinity changes at resistivity-image bottom moving up the image for two seasons' (wet and dry) conditions. The salinity changes are believed to have been caused by incremental tide passing through highly porous material in the active-salinity-change area. The study's results were used to plan a strategy for sustainable groundwater exploration of the island.
